The listing, 1970s Topps baseball cards (placeholder condition, check description/photos) has ended.
This will be a lot of four cards, each of them have its own set of problems. The two 1970 cards have the worst wear; #181 (Sparky Anderson, a HOF manager) has parts of the center back ripped away, maybe from being taped for all I know, and #67 (RBI leaders, all 3 pictured players are in the HOF) is incredibly creased all around. Not as bad as some cards from the early 50s can be, but still may hold some collectors back.
The other two are in much better condition in terms of card stock. 1971 #67 (ERA leaders with HOF pitcher Jim Palmer) has average wear for the year, but has the three Red Sox pitchers' averages underlined on the back [found at a card show in MA]. And 1975 #331 (checklist featuring Frank Robinson as a manager) has all but one checklist box filled in, but otherwise in fair shape for its age.
As soon as I have an address to send the card to, I'll get it in the mail, but will inform you if I need to delay sending it out for any reason. It may not be a lot of perfect cards, but maybe they can still be a solid part of your collection too.
