FYI:
Both dye sub metal and acrylic face mount prints are beautiful in their own unique ways but neither are considered "archival" each due to different reasons, if that's important to you. Metal, being dye based, has a rated display life of about 60 years and face mounted acrylic, if made using double sided film, will separate over time, especially if subjected to temperature extremes (such as being shipped in very hot UPS/FED X vans), as the print, film and acrylic all have different COEs. There is another method of creating a face mounted print using a proprietary method that gets around this problem (I forgot the name but no doubt other here will mention it) but it's very expensive.
The other problems with these prints is that the acrylic scratches very easily (yes, even the "scratch resistant" version) and the metal print's edges are easily bent because they are printed on thin aluminum sheets (they have to have a frame around them to protect them).
