William Painter - was the guy who invented the Crown Cap in Baltimore, Maryland. USA in 1892, he may have also been responsible for the Crown Topper Hairpiece for follically challenged individuals (they have a similar appearance and perform roughly the same function i.e. covering up an open area above the neck!) Crown Caps are also popular with model makers who flatten them and make things, also World-wide Collectors like them for the variety of designs they can carry. Useful, interesting and collectable!
