Most of the Nixon memorabilia there are cute and harmless, such as the Presidential Yo-Yo (trivia: in 1974 Nixon was the opening yo-yo act at The Grand Ole Opry; that signed yo-yo later sold for a record $16,029), Future Commander In Chief Bib, or the Air Force One Playset ("Tax policy might not excite the kids, but this 30-piece die cast metal Presidential transportation set will.")
Some seem to have been chosen for their dark humor potential:
Turn your room into a spy headquarters, and keep it safe from enemy agents. Inside the spy case you'll find everything you need to detect intruders, listen in on secret spy meetings, and pass on classified information.
Assemble the components to make a range of super-sleuth gadgets, including a movement detector, a pressure pad, and an intruder alarm. The kit also includes a ready-made listening device, an invisible-ink spy pen, and a spy training manual with instructions for carrying out the ultimate in top-secret missions.
(What? No Lil' Plumber Playset?)
And then there's the book Richard M. Nixon and his Family Paper Dolls by Tom Tierney:
(If kickin' around with Tricky Dick in his skivvies isn't your cup of tea, Tom Tierney also has paper dolls of other presidents and their families, including Reagan (w/Bonzo) and the Bushes. Heads up for you political snark miners on the last one: be sure to Look Inside!™ for a young George and Laura modeling vacation wear.)
The Library shop also has an entire section dedicated to The Day Nixon Met Elvis. Now you can get the famous picture of Nixon and Elvis shaking hands ("the most requested image in the history of the U.S. Government") on a mousepad, note cube, or float pen.
True Nixonalia aficionados will want a bird house in the shape of Nixon's boyhood home. Or if you have always longed to live out your Nixon role playing fantasies, why not get a reproduction of the presidential desk for a mere six grand? (No word if it comes wired for microphones.)
Lastly: Looking for AFDB camouflage? Try this stylish Nixon Beanie with the classic Nixon oval surf logo. No one will suspect your paranoia when infiltrating GOP conventions in that (DNC infiltrators, go here.)
