I have a few autographs - Heath Ledger, Christopher Lee etc.
I quite like framing cloth maps - like LOTR, Witcher 3, God of War etc.
I have a few heavy duty real cinema display posters - they are fantastic, made from either heavy duty plastic or silk, they are also HUGE the one I have advertising the LOTR: ROTK is of the Witch king and its the size of a door, also have a lovely Japanese silk one for Fantastic Beasts with some nice Japanese style artwork of the different magical creatures - both from Ebay.
I have a few MONDO posters - they are beautiful but expensive.
I have a few ideas that I am working on now:
1. putting magnetic strips on the wall and displaying my steelbook collection. Movie steelbooks can be stunning and it seems like an ideal way to show them off.
2. If you have a vinyl collection you can buy wall mounts for them to show off their artwork - I have a lot of movie soundtrack vinyls with beautiful art I want to display (mostly from MONDO, Waxwork Records, Ebay)
3. I am currently buying comic books with particularly stunning covers, or best represent characters that I love, and am going to place a few of them strategically in either overly-large frames or between two large acrylic sheets held together by clasps and mount them on the wall. I'm very excited for it, I have spent quite a lot on the comics all together, but the effect will be wonderful.
