Leth@bookstardust @youronlyone Yes, as long as your sticker is based on the public domain version of the character. You can make whatever changes you want that don't infringe on later, still-copyrighted versions of Disney's Mickey.
And tarnishment specifically means that you're using *a mark you made* that is *similar to* the famous mark in a way that harms the reputation of the famous mark. The art on the sticker is not a mark, so it can't be tarnishment.
(But I'm speaking from the American perspective, so the details might differ where you are.)
