This shirt is adorable. It's a body double with a motorcycle wearing a mustache! It was even worn by baby Joe on Modern Family the other week. The only reason I'm selling is because I didn't realize that I bought size 12 mo. by mistake. Just bought another a size up. I already cut the tags and washed it, and my son wore it once, so it's practically new.
You could buy it new now from GAP for $20 incl. shipping. Will sell for $10 + shipping from northern California.
