Dada Magazine (1917-1918)
The original Dada magazines are available online on the best art resource website, ubu.com. The magazines are all pdf's so you can save them and print them. The collection is seriously mind blowing and is well worth a hour or two of your time. And the rest of the site is a treasure trove of rare and very obscure art works in video, audio, visual and writing. Hats off ubu!
