John W. Golden (the artist behind the popular "By Order of the Management" series) is holding an Etsyversary BOGO sale from now unti July 23rd. That means when you buy one print, you can get another one for free (limit two free prints per order).
Although one of our Nested responsibilities is to narrow down options for our readers, we're at a lost when it comes to picking on the print we're liking best. But if we must, definitely check out the Fido Series and Critter Series. We'll probably be picking up a print of The Hirsute Hedgehog and The Sensible Owl.
