This plaque is exactly 4" by 5". I found it (loose) on the floor of a back room of a building in North St. Louis. We were remodeling the building in some fashion. The year I found it was probably 1968, so I've had it for 40 years.
I have googled this thing 6 ways from Sunday, and haven't found anything or anybody, resembling or related to FF Hoffman.
Certainly u may post it. I have enjoyed the marker for 4 decades, but would be willing to sell it, and always wanted to find someone like yourself that really thought it was awesome, too.
BTW, it is unused, IE, it was never removed from masonry, it was just never installed. I always assumed that it was placed into brick walls; but do you think it was installed into cement walks?

Sent by Rich who found this blog while doing a search. I'd love to buy it but it must go to the St. Louis Building Arts Foundation. I thought it was a sidewalk plague.
