JB Hirsch

I have spent much time trying to figure out these bookends. I had the sense they are deco but not quite. I've narrowed down to an exact match to a pair of gold painted JB Hirsch that I discovered online with Chuck Decosta's Antiques (web site). Now I think I know my bookends were cast from this mold. This is fun following the information as obviously I am an ametuer in my knowledge. Any further information I would love to know. My guess is they are made in the seventies from the mold and that they have had some rough wear. Maybe they are art deco as the colors coincide. I bought at auction for not much money as I like the look.
I have learned a lot about different sculpture makers in my search.
