Allow me to kick off April with these two cards...
The first is the 78 Brett. One of my favorite close up shots in all of Post War cards. I have owned so many of this card since I was a kid, and this is the cleanest copy I ever have come across. The borders and his face are totally free of the PD that usually plagues the card, plus the centering is there.
Next up is a nice and square #660 Aaron Mini; the card is so often diamond cut. Not to mention OC. Found this squared up beauty for around twenty bucks on eBay!
