I was lucky to finish the set while it was still pretty obscure. Those, the 84 Topps Encased, 85 Topps Minis, 88 Topps Cloth 89 Topps Big Head Suckers and Topps 89 Mets/Yankee proof DHs were the toughest 80s sets for me.
It would be interesting for someone to try to complete the 82 set in gray transition cards....but not me
