Simple, 3 color entry with an updated-vintage edge. #3 is distressed, #2 is clean. Logo could easily be easily made to a single color logo for keg stamps, coasters, beer merch.
HI - here's my next round. I have a 70s/disco-ish chick (tried not to make her TOO 70's/disco cheezy) in holding up a glass of ale with a hop/disco ball! On the can, I was thinking the hop disco ball could just be can/aluminum colored. I took all the black out, so the design is white & your PMS red/gold/green - (and "halftone" versions - that way it's still the same screen/color) which should help to keep cost down. If you screened it on white, it's only be 3 colors!
