Sidewalk Concrete laying company plaque - Simpson Bros. Corporation 1930

"Trade Mark Reg. Laid by Simpson Bros. Corporation 77 Summer St. Boston"

"1930"

A combination of 2 plaques indicating the sidewalk concrete company and the year.

There other plaques in the same sidewalk of other concrete companies!

Obviously a beautiful nerdette (or nerd) went to great length to collect and set them back in fresh concrete!
