TCMA pumped out six different All-Time sets in 1980, using roughly the same format for the Cubs, White Sox, Yankees, Tigers, Giants, and Dodgers and most say "All-Time [Team Name]" on the front somewhere. The Yankees are an exception, showing only the player name and an old-style portrait frame. It's an interesting enough set, though there's no problem finding other oddball examples for most of the players—and probably with better pictures at that.
Value: I pulled this Ruth a few years back from a dealer's $3 box at the Fort Washington (aka Philly Show) card expo.
Fakes / reprints: Not even Ruth and Gehrig make this kind of set worth reprinting, so the risk is pretty low!
