The first five buttons are each 3" and c. 1970s. The last in this group shows famous animal trainer with his facsimile signature Gunther Gebel Williams. This has a little brown stain on the right side with just a couple of pinpoint darker spots. There is also a tiny bit of faint age on the Ringling button with pink bkg. Last item in the group is also c. 1970s but reproducing an image from an earlier poster. This is 2.5".
