Hi
Thanx!
As I said in the intro - these panels were probably a warehouse find - never used in the production of the product - thus they're not bent.
Here's a Yount on eBay for 24 bucks:
Haven't checked yet but I'm guessing the 75's are more plentiful as a complete panel compared to the later issues.
It would've been super if they had used Brett in 1975 to go along with Yount.
