Bikes are Bisexual t-shirt with 3D ink

I got the idea for this sweet double-printed Bikes are Bisexual tshirt with “3D ink” from my childhood days playing video games {etsy}.

It was the original NES, and one of the first games for it, Rad Racer, came with a pair of 3D glasses—the kind where one eye was blue and the other red {wikipedia}.
