Since Feldman used an 'Indianhead' image on the other items we found online - I mocked up a 'REGULAR' version just for fun.
I used the Ethyl lettering as a guide to create the 'REGULAR' lettering for this image and created a (much) nicer 'head' logo for the center than what was shown on the web.
As I mentioned, this was just me making a fantasy image based on a real company.
