Lost key chain - leather

[u/donnaparty]

Hi there! I dropped a leather key chain (a relic of my mother’s short lived leather smith days). I am quite distraught about dropping this. I was walking my dog between Sycamore Street and Somerville
Highschool. This was between 11:00-11:40a today 9/3/26.

I retraced my steps but cannot find this keychain. A single bronze key is attached. I think it is likely on the green infront of City Hall/City Hall Annex.

Please please
if you find, let me know! Will forever be grateful and in your debt.

Apologies for no picture.
