I recently landed one of the tougher Zack Wheat items I still needed for my collection of the Brooklyn Hall of Fame outfielder. It's one of the rarer pieces to find in my experience -- I've only ever seen a handful -- and definitely one of the trickier to find in presentable condition as the card was made on thin, glossy stock. It is extremely susceptible to chipping and other damage.
Patience was necessary, although the pickings were so beyond slim I didn't have much of a choice. After missing on a very nice SGC copy the above PSA 2 eventually showed up and I jumped.
