I don't have pics but I have a few smaller posters in my MLP corner of my room. I have the two-sided poster of Princess Luna and Nightmare Moon that came with the lunchbox with trading cards, I have a poster I got from the first Rhode Island MLP Fair in 2008, it doesn't say MLP Fair 2008 on it or anything just has a basic group image of the mane 6 and Princess Celestia.
I also have a pamplet from a G3 box that has the Crystal Princess ponies line with Rarity's castle. All the ponies are set up with a nice scene (actual ponies not animated ones), I decided I wanted to put it on my wall as a poster.
