Crown caps have been used on bottles since the 1890's -
100+ years - wow! How about that! In fact the Crown cap was
patented in 1892 by William Painter, an American of British
decent who in his lifetime took out over 80 different patents.

Over the hundred plus years a multitude of designs of cap
lifters have been manufactured. From quirky figural types,
depicting pretty much every animal you could imagine, to
advertising for Beer producers - well that makes sense. Also,
many famous people can be found on Bottle openers as well
as historic buildings, places, effectively souvenirs from here,
there & everywhere. It's likely a lifetime devoted to collecting
cap lifters would only scratch the surface of the 1000's of
different variations of bottle openers that were made.
