The Magical Bulletin was published between 1914 until 1925, followed by a very brief revival in the late 1940's. Magicpedia has a scan of the front of the first issue here. For a small fee, Magic Nook has scanned PDF copies of several volumes you can read through on this page. I was hoping to find an actual copy somewhere, but don't see one. Sometimes looking through this stuff just makes me want to go and collect even more!
I am not sure if I prefer the devil jumping out of the hat, or the terrified small fuzzy creature.
