GasHouse---good example on the 56 Teams. Another is the 74 Washington/San Diego cards.
On the 73 Manager cards I had not known if the different backgrounds were intentional( like the change in printing company made by Topps to correct the 62 greenies) or just unintended printing deviations. Have you heard or read something about that ? Others I have wondered about are the 58 Yellows and the 69 Whites...were the changes intentional or mistakes ? Looking for any input on that. There are some gray areas for any definition
On a newer front I have the 4 SCD Catalog listed yellow names and one no name listed in the 1980 Topps set ( plus a 5th yellow not listed..McEnaney), but those again would seem to only be print defects---like the no name Thomas and related cards from that sheet with blank spots
Still, I won't pitch them, or the Herrer, or the Bakep, or the Campos...unless Bob L starts yanking them from the Catalog
