Struggling to find the perfect gift for your human? May I suggest taking a look at the wonderful website http://shop.lingvistov.com?
Landysh the artist initially used doodles to illustrate the Lingvistov School of English via Skype which is run from Russia. The school still exists but the interest in his quirky amusing doodles prompted the start of the Lingvistov shops which sells calendars, cards and prints.
There are a lot of doodles featuring cats if that's your thing (not mine - good for chasing end of)but here is my favourite dog doodle with an inspirational message to get you through the working week!
