1950s Baseball Buttons Complete Store Display Sheet

I ran across this super cool cardboard display sheet, advertised as being from the 1950s, in an older auction catalog from December 2000. I’ve found a few more examples online, but with no additional historical info.

The copy above was described as an 11” x 16” cardboard display sheet featuring 144 assorted 3/4” pin-back buttons still attached. It included a bunch of “Team” pins of the White Sox, Browns, Red Sox, Tigers, Phillies, and Dodgers, along with a few “Slogan” pins, including a bunch of “I am a Yankee Fan” and “I am a Giants Fan” examples. The sheet was described as being in VG condition, while the buttons were mostly NM/MT.

Inside The Park Collectibles auctioned off the following example in June 2021. However, it went unsold with a $350 minimum bid.

They mentioned it was the first time they had seen the display, which they described as “50’s/50’s.” They also said the display was 12.5” x 15”.

I still have a few button books to pick up for The Hobby Library, so in the meantime, if you know anything about these displays, please share!
