Propaganda: stickers and posters
The following two stickers are free for the asking. I put them on my laptop. Under heavy wear and tear (in and out of a backpack at least once a day), the ink begins to wear off after a couple of months. The stickers can be peeled off, though getting all the glue off takes some effort.
