Think I’m going to try and replace the plexiglass with no reflective glass. I have some family that owns a frame shop so think I can get a piece for free. 

 that's a good idea. glass looks much better on my other posters. mine is plastic and it is super reflective. 

 You can get 2mm non-reflective picture glass, it’s not bank breaking and most likely worth it for something you like to look at on a regular basis
