Patreon Exclusive: Charlie bonus content! (Patreon)

If you were reading the last Charlie's strip and you would like to see  the photocopied butt of Charlie, here it is only for you, my beloved supporters!

I thought to find more references to make this drawing but surprisingly google is not so full of references for photocopied butts, but if you search for people in the act of doing it, you will find a lot of references!
