Glad someone else appreciates this era of the Reds! You should post some of your pieces.
Here's another late-30's piece I picked up on the cheap. Huskies cereal dated 1938 and put out just after Vander Meer pitched his back-to-back no-hitters.
A little rough with a corner missing, but I couldn't pass it up because of the great illustration and colors.
