Proper Poster Framing Technique?
I've read several articles from various sites regarding do's and don'ts for framing original posters. Several of the most common issues seem to be:

• Archival Plexiglass
  
• Archival Mat
  
• Archival Backing

However, I have not found much information regarding how to properly mount/mat a poster in order to keep it from touching the glass/arcylic, which I have read is important. From what I read, it seems as if the poster itself should be glued to a matting or foamcore so that it does not come in contact with the glass/arcylic. However, would this techinque not ruin the poster, by using adhesive to mount it to the foamcore? Perhaps I am overlooking the obvious or just need a simple drawing, which I could not find, to explain the proper technique. If anyone could explain the proper technique to frame a poster, I'm all eyes.

I had my frame specially made at a framing gallery. I have an alluminum, copper colored frame around my "Outlaw Josey Wales" Poster. I had it matted to a board (that can't be seen), and ultraviolet protective glass, to keep it from fading. It's pretty damn sweet. I'm doing the exact same thing for my "High Plains Drifter."

I looked into a bunch of different possibilities, and finally went with what I thought looked the nicest, combined with value. To have it framed cost me $75.
