Just mounted 5 contacted printed 5x7 B&W silver prints (vertical format) together in an 8in x 40in vertical mounting. Pictures are of an old homestead house that I've been documenting its demise for the last couple of years. At first, thought it would be weird, but the wife-unit (aka keeper of my photo play monies) insisted on this. She had a particular spot in mind, and lo and behold, if it ain't kinda cool for a wanna-be artsy type. I also contact print 8x10s, but they don't have the same framed look as 5x7's.
