I’ve always been fascinated by this relief on the entrance to the building at 500 Saint Jacques. The building itself was built in 1960 (or so, some places say 1959) by the firm of Ross, Fish, Duschenes & Barrett, which has now become DFS Inc.
I’ve written to them asking who is the artist who created the reliefs, but have not received a response as of yet. As soon as I do, I will let you know.
