Take a look at shop.dieterbrehm.com for stickers (and in the future, merch and other analog artifacts)! I ship all of these items personally, so please be patient. I will ship out at least once a week. See below for some of the items offered and click through to the site for more info.
I sell a number of prints over at inprnt, an on-demand printing site with many high quality formats. In the near future, I'll also be offering original works, so please look forward to it! If the print you're looking for isn't available here, please reach out and I'll be happy to arrange something! for each illustration you can get cards, posters, canvas prints, and frames if you would like.
Take a look at inprnt.com!
