Some of you may have seen my recent post in the "Prince Autographs" forum about the new Prince signed poster that I just acquired. I initially had put it in a huge toploader. The poster is 23x35. Paul had suggested I be careful about toploaders as they often contain PVC which could damage the poster. Now I've used them for years on photos without any problems. Plus BCW, who makes the toploader, says that the PVC in their toploaders is not made with a plasticizer and will not harm your posters. Well, after just two days, I noticed an area just starting to get a little spotty, although it's still not really noticeable. So I decided I wasn't going to take anymore chances, and I removed the poster from the toploader - not an easy task, but now it's out.

So earlier in the day, I had talked to a local frame store, and the owner said he could frame it up with museum quality materials and UV glass for around $225-$250. He said he would permanently mount it to a board and frame it museum quality.

So I please ask for any recommendations from the experienced people here. Should it be permanently mounted to a board? I think he was saying that so it would not develop any waves in the poster. Is that a good idea? I just want to protect it as best I can. I've got quite a bit invested in it as is.

Please help. Thanks in advance. I'm not too experienced with framing.
