Clint Eastwood/Dirty Harry movie poster w/embossed Warner Bros Limited Edition?

I found this at my local thrift store today. At first I thought it was an original one sheet movie poster because it measures 41" x 27" , but at home looking it over more I saw an embossed Warner Bros. Inc. Limited Edition 1987
I've tried image search and asking Google AI different ways, but I can't find anything on Warner Bros. making a limited edition reprint of the Dirty Harry movie poster? I asked if it came out with the video & again it said there was nothing about Warner Bros. making one.
Has anyone seen this before?
Is it a limited edition/special poster (Clint Eastwood movies still have fans in the U.S.)?
Thanks for any help!
