I worked at Treyarch for a time. While I was there, every employee received a selection of very high-quality posters. They are about 2'x3' and printed on VERY thick card stock. So thick that you really would not be able to roll it up in a poster tube without damaging it.
The one pictured above is the only one I kept, and I've decided I no longer have room for it. It has the names of all/many of the people who worked on the game printed in the background. I beleive these were only given to Treyarch or Activision employees.
Does anyone happen to know if these hold any value to collectors and what that value may be? I have not been able to find any listings or sales of them online.
