1960s Psychedelic Hippie Folk Art - Rick's Construction Helmet

What Rick did to his ordinary yellow construction helmet 40-50 years ago is - well - OOAK. Painted the yellow a strong green then using a complimentary hot orange color proceeded to zig zag with arbitrary shapes all over his helmet. I choose to think these are not the patterns he was seeing while working - especially on a skyscraper.... but... Could have been a recycling of old equipment (helmet) for use in a protest or outdoor concert - we will never know. Pretty cool artifact of the era regardless.
