The following is from within a thread on 12 O'Clock High! and is in response to a question about a wartime map:

I deduce that you intend to have your German map framed for display. As an archivist, may I caution you against the display of the map you have described. Continuous exposure of paper, especially poor quality and/or old paper, to light will rapidly degrade both the printing and the stock itself owing to the effect of ultraviolet radiation present in ordinary lighting. A certain measure of protection may be obtained by utilizing special filtering glass, but this is expensive and has a finite effective life. If you value your relic and care about its preservation for future generations, don't display it on a day-in, day-out basis.

What goes for display of Fritz's map also goes for prints and lithos.
If you want to retain the bright freshness of color in your
famously valuable signed litho of ga-zillion victory ace Otto von Whoshedorf in his Bf 114Q, better think about the ultraviolet in the surroundings. This is especially true of flourescent light sources.
