As seen in numerous episodes of "Star Trek: Enterprise"

I acquired this from a private collector.

This is a bona fide piece of Trek set dressing, obtained through a private collector. This was made by the art department over at the 'mount for sets and props to be used on Enterprise. These stickers feature the standard "Enterprise" ship logo design that is seen throughout the series. These are not fan produced. These are the real thing. This appears to be printed by an inkjet printer onto a decal type paper. If you watch Enterprise, you can see stickers like this all over the ship. I have not peeled it off its backing, which explains the white part sticking off to the left of the sticker.
