Thanks for everyone who entered. Was so cool to see how many of these characters people remembered, some especially were incredibly rare. The winner of the competition correctly identified 35 of the 50 characters.
This was a really tough competition. Most of the original posters are not able to found online, some of the characters look very different, in some cases there are a couple of posters for the same event, and in one case (to try trip some up), two characters from the same poster.
The full list is below. For the tours I accepted the entry as long as one correct band was listed.
There were only 3 characters that nobody guessed correctly.
20 The octopus with balloons was from CALH2011 (By Sei Rey Ho). Super tricky as I'm pretty sure I only ever used that one briefly and on social media.
46 (The Nose) was from CALH2013, the official tshirt (By Nicholas French) where the Camp A Low Hum type was made out of noses. You can see part of that poster on my Youtube channel
49 was from The End of Puppies (By David Kilgour). This poster was only online for a short while and was a teaser until I announced the line-up with a different.
