A descent into #manholecovermonday madness in five covers. Every few years, #SomervilleMA went for a new look on their standard SSSS covers. Here’s a plain one. S’s are in a tight square in the middle. San serif. 1/5

For #manholecovermonday I think this in the public garden is possibly from the Boylston street subway (1914). Maybe from the original Tremont st subway (1899) though at this location (foot of Kosciuszko’s statue) it would have been a subway-to-surface incline so I think less likely
