Chart of Electromagnetic Radiations
You cannot buy this amazing Chart of Electromagnetic Radiations anymore, but thanks to the folks at Lawrence Livermore National Laboratory, extremely high resolution image files of it have been placed on the flickr website. The chart showed up in Popular Science magazine recently. W.M. Welch Manufacturing Company (now Sargent Welch) originally sold the wall poster in 1944, so the content does not reflect knowledge gained in the last seven decades, but its sheer artistic beauty and amazing content is enough to bring a tear to a technophile's normally staid eye. Even if you do not print out and hang it on your office wall, you owe it to yourself to at look at the 10000x6958-pixel version. The camera used was undoubtedly a little higher quality than my personal point-and-shoot mode.
Unfortunately, Sargent Welch no longer sells this chart; however, they do sell many other very fine charts that you might consider, including a newer EM spectrum chart.

Dial-up modems blazed along at 14.4 kbps while tying up your telephone line, and a lady's voice announced "You've Got Mail" when a new message arrived... |
