E121's are tough and there are numerous poses and variations. The pitching pose in red sox uni seems to be the most popular.
I didn't see the auction ending late july until today...22.88K for an e121 "babe" ruth in vg. This one just ended...a similar vg ended at $14,700. Some strong prices for some tough early ruth cards.
