Just found there are two variations of the paper Pete Bingo Gold 5 paper card from the Fremont Casino in Las Vegas. On one version the reverse text is 48mm top to bottom and on the other the reverse text is 50mm top to bottom. There's a slight difference in the spacing on the front text as well. This is definitely something you would probably never notice without having both version side by side.

Here's scans of the smaller card followed by the larger card...
