Large and bold 3.5" button from 1966 by company "Button World" with their name and copyright of N.P.P. on curl. Upper left has tiny raised bump caused by bar pin on back and lower right has a single very faint 1.5" hairline scratch showing only in reflected light. In spite of these two small defects, this is the best example we've seen with exceptional gloss and intense color. The thin celluloid on the buttons from this company is very susceptible to wear and this is an outstanding condition example.
