It looks like they have chosen an official winner for the Bronycon Documentary poster contest. A ton of people entered, but only one could claim the highest prize. Rebekah Wicklund will be walking away with 500 dollars and a meetup with Lauren, Tara and John at Bronycon. If you want to check out all 342 entries for the contest, hit up this page! There are some amazing ones, so definitely take a look!
If you submit one to the contest, feel free to send it to the EQD box for drawfriend, though it will be strict as always. I see at least 20 in there that are straight up amazing artwise, though not really in poster form.
(Seriously, send those posters!)
