Here's an article about the LSD Museum in San Francisco which houses a tribute to the early LSD era including blotter art, day glo posters, and a wide range of memorabilia from the times. One interesting thing in the story is that the guy who set it up did it with the help of NEA grants (National Endowment for the Arts) under Carter and Reagan. http://www.huffingtonpost.com/2012/06/29/san-franciscos-lsd-museum_n_1635907.html
