Amazin' Avenue, a New York Mets community

My uncle (who was my main ticket to Mets fandom) gave me some of his old Mets stuff awhile back, and I finally found it again when I was packing some stuff up to get ready for a move. I have no idea where this is from, but it's a whole poster series of 1973 Mets starters, and then on the back of each of them there is a Lil Abner comic. Anyway, this one is Cleon Jones. More forthcoming.
