This one is from season 2 episode 21 called “Three Me and a Comic Book” where Bart, Martin, and Milhouse pool their money together to buy a copy of the coveted Radioactive Man #1 comic book. A the beginning of the episode, Bart attends a comic convention and the doorman wears a shirt that where the logo resembles Captain America’s logo. While I could have drawn a perfect star and such, I decided to make this look a bit like the cartoon and made it a bit wonky.

Here’s the link to the product as a sticker, but you can view the design on multiple items if you’re interested.
