So, a little late in posting this (apologies, work held a big annual event and I got tied up in orchestrating that)

A rather unassuming cardboard envelope arrived in our mailbox. However the contents were both Algebraic and entirely Math.

They are art from Drawings by Nicole (www.drawingsbynicole.com) - one a print, and one an original piece of art. Both are actual treasures, of the kind Finn and Jake would seek in a dungeon (or more than likely just stumble upon while goofing off too)

First up the BMO painting. BMO is tied with Ice King as my favourite character in AT. So to have such brilliant art - well, oh my glob!

As for part two, well, my wife loves AT as much as I do. Her favourite character is, without a shadow of a doubt, Peebles. And she ships Bubbline too. So this is perfect for her!

The only thing that makes me sad about this gift exchange, is that the redditor chose to remain anon, and I want to be able to thank you properly. But I hope you're reading this. Thankyou so much! When we move, we'll hopefully be buying our first house together, and this art will be taking pride of place on one of our walls. In the meantime, it will be taking pride of place in our rented flat!
