Basically, they introduce at least two new editions a week: one photo and one work on paper. Most are available in three or four sizes. When they first started, the smallest size was reprinted in the largest batch — an edition of 200 — and sold at the lowest price — $20. Hence the name 20x200. They sell other sizes and even the original artwork at other prices but they have some awesome pieces for only $20!
Here's a few of my favorites:
There are so many other amazing prints, you definitely need to take a look and support this incredible project!
