It started with a souvenir mug many years ago and the interest has never left her.
Caroline Scott is the Glaswegian behind one of Twitter's more joyous and inspiring feeds - Glasgow Coat of Arms (@glasgowcoa).
Glasgow's civic insignia and the stories and people behind it hold an enduring fascination for Caroline.
Now the 53-year-old is about to open an exhibition of images she has collated over the years.
She has also developed an online map that records the places where the coat of arms can be found.
Like many Glaswegians, Caroline learned about the story of St Mungo and his miracles at school.
The stories of the bird, tree, bell and fish are engrained in the civic pysche.
But it was Glasgow's celebration of its burgh status that sparked the seed of interest as a young girl.
'Triggered'
"It started in 1975, the year of Glasgow 800 - the 800th anniversary of Glasgow becoming a formal Burgh.
"All the school children got a mug as a commemorative souvenir which had a very 70s style coat of arms design on it.
"I think that's what triggered my interest, and I've taken snaps over the year - but I've never done anything with them."
Caroline, who lives in the Southside, has had a varied career.

How Twitter has taken to Glasgow Coat of Arms
She developed her interest in the city's buildings and heritage at a firm of architectural ironmongers.
Time at a land survey company developed her love of mapping.
Now the two interests have come together - first with the Twitter account, and now with the online map.
"I am not an historian.
"I haven't had time in life to do lots of research, although I have learned a lot since I started the Twitter account."
She adds: "When I started the Twitter account I was able to post the photos I had, and then there was a bit of interest and other people were posting them.
'Clever'
"I put on the Twitter bio 'contributions welcome' - and the reaction has been absolutely brilliant.
"I think my inspiration was probably 'Tenement Tiles' - they have been doing their thing for a while."
Caroline has amassed around 400 versions of the coat of arms - but that includes all sorts of finds.
Many of the examples have been submitted by followers of the Twitter site.
Not all of them adorn bricks and sandstone, though.
She says: "A lot are from buildings and interiors of buildings and stained glass and so on.
"But some are just fun. Bricking it Glasgow (another Twitter feed that pays homage to Glasgow's iconic buildings in Lego) made an especially clever version.
"And several people have posted Glasgow coat of arms tattoos, which is great."
Her hobby has a purpose, she believes, when many buildings face an uncertain future.
She says: "The built environment doesn't last forever.
"Buildings come and go, and a lot of these beautiful things are going to be lost to demolition, or erosion.
"Springburn Public Halls was demolished in recent years and there was one lost there, and it was an absolute cracker from what I have seen from old photographs.
"There are a couple along Trongate that are terribly eroded, you can barely make it out.
"Sandstone being what it is, there are others that are not going to be around for much longer.
"Various fates await these things and I think it's just good to have a record during times of change."
Victorian writer and antiquarian Andrew Macgeorge was responsible for the city's modern-day coat of arms.
In 1866, he brought all the disparate emblems that had previously existed into one formal design.
Since then, the city has worn its civic badge with pride.
'Odd thing'
Caroline says: "Glaswegians really take this coat of arms to their heart. It's an odd thing.
"After 1866 and the first formal version, Glaswegians have just gone off and done their own thing.
"I just love all the different versions, and everybody's just got their own take on it.
"There are as many takes on the coat of arms as there are Glaswegians.
"It's an identity thing."
And Caroline offers no apologies for wrapping herself up in a symbol of her city.
"I think there are worst things than taking your home town as an important part of your identity at a time of arguments over Scottishness and Britishness and Europeness, and all the rest of it.
"Whatever we are, we are Glaswegian, you know - and that's my take on it.
"I think it's okay to have that civic pride, I think it's great, I think we need it especially during times of change and challenge."
Contributions to the map have come from across the divides. MPs Alison Thewliss and Paul Sweeney and Green councillors have contributed.

Versions are recorded at the city's Catholic and Protestant cathedrals.
She says: "My day job is now in politics, but this whole endeavour has been a lovely escape from the day job.
"It is very much a hobby and it's just been lovely and a diversion through these political times."
When Caroline wrote to the city council several months ago about her interest she never imagined the reaction.
A meeting was arranged with the Lord Provost who took an instant interest in the project.
Last week Eva Bolander hosted a civic launch for the online map at a reception in the City Chambers.
Among the guests was the First Minister Nicola Sturgeon who is a fan of the Twitter site.
She said on Twitter: "Really enjoyed the reception in Glasgow City Chambers earlier for @GlasgowCoA
- such a great & developing archive of a wonderful part of our city’s heritage."

The Lord Provost told Glasgow West End Today: "The stories around the miracles of St Mungo are ones that people like to hear.
"Glasgow has a very particular identity and this coat of arms is a wonderful symbol of the city, which people really identify with."
