My girlfriend is a graphic designer and was asked to design a t shirt for a local car show
They were open to ideas, and she asked me what was an iconic hotrod?
I thought about it for along time....... 57 chevy?....mustang?...... T bucket? No been done to death
40s willys gasser? Yea that's the one!!!
After about 8 hours rendering it into a really kick *** t shirt, she submitted it for approval
They replied back "we like it but since its the 50th anniversary of the chevy camaro could you do a camaro?"
WHAT?!?!?! camaro came out in 1967 not 1969
I've got to go to this chitshow car show, maybe put some SS emblems on my duster and everyone will think it's a Nova
