Some of these are from Negative One, the webcomic, and some of these are from the THTIB series. These are colored cartoons that can be printed on magnetic paper to make your own. Choose a character to see the magnets.
(Note: Yes, Dax and Weaver are the same in both sets. They don't look any different in the "present" of the books, so their magnets stayed the same. Adele has a different hairstyle, so her magnet changed.)
