From the 26th season of Survivor, Survivor Caramoan - "Fans vs Favorites" which aired in early 2013 comes Erik's letter from home envelope, in episode 11 all the remaining castaways were given $500 to spend at the traditional Survivor auction where Food, Rewards and Idol clues are sold. One of the last few items to be sold were letters from home, the price to get them was $20. This is the envelope that Erik's letter from home came in. Survivor Castaway Erik (lasted 36 days this season) sold a number of pieces after the season ended.
It can be easily matched up, by the 3 darker panels midway through, a darker pannel near the top and the torn part between the I and K in his name.
Sorry I took the pictures from the episode off my TV.
I'm always on the hunt for Survivor items, feel free to leave a comment or check out my other items. Also very happy to chat with other Survivor collectors :)
