2-3/8” tall oval. Reverse marked with stamp of maker W&H. Button does not include any school name or initials but is inscribed “Feb. ’41.” Button has slight raised ridge at center a little noticeable to the touch and caused by the reverse bar pin. There are also about a half dozen very tiny indents in the celluloid surface and the cream bkg. is probably a little darker than when issued but there is no obviously dark spotting or stain. Very limited issue. Fine and Rare. First we’ve seen.
