For the "Beautiful Forever" show that Light Grey Art Lab held back in March. The entire show focused around tattoos, both permanent and temporary. Other than that, the subject matter was completely open. I mean seriously, who wouldn't love a famous internet cat somewhere on their body? Don't lie, y'all.
Fun fact: I met Mike Bridavsky (the famed owner of Lil Bub) and was able to get a copy signed as well as hand a few extra prints over to him and Bub! Life. Made. Forever.
