Here is a cover of Family Computing (an 80's magazine that featured CoCo 
programs in BASIC) that I scanned and ran through both MGI Photo Suite's 
oil paint filter, then loaded into LVIEW and dithered down to 128 
colors.  You can see how the tarnished image improves with little 
effort.  I haven't tried it on higher detailed pages yet.

Another excellent option that would require way more effort is to use 
Macromedia's FLASH software to vectorize the covers which would allow the 
peeling away of yellowing, splotches, or other blemishes, as well as allow 
the perfect resizing of the pages.
