1973 TCMA All-Time New York Yankees Team Set?
I purchased some items from estate sale and came across some post card like items that I finally determined was the 1973 TCMA All-Time New York Yankees Team Set. I have only found one website (https://www.tcdb.com/Checklist.cfm/sid/170321) that mentions anything about them. No sales anywhere that I can find. Anyone know if these are collectible? Thanks much!
