WWHRD? was created by cartoonist Mitch Clem and is available on t-shirts and stickers at Silver Sprocket. It was inspired by two of Clem’s webcomics in his series Nothing Nice to Say WWHRD?#299 and WWHRD?#337. If you scroll down to the bottom of the Silver Sprocket merch page you’ll find a photo of Henry holding a WWHRD? sticker!

Cheers to Stuart for suggesting this post.
