Private Eye celebrates its 50th birthday next month and appears to be in rude health, bucking the downward trend for magazine circulation in the digital age.

The anniversary is October 25 but the celebrations start on Tuesday (September 20) with the release of a new book Private Eye: The First 50 Years, a history of the magazine written by the Eye journalist Adam Macqueen that charts its rise from 300 copies of the first edition in 1961, below, to a fortnightly circulation of more than 200,000.

The book features interviews with key players in the Private Eye story, rare archive material and unseen photos. (There are some “seen” ones too.) And, of course, there is an abundance of the cartoons that are so central to appeal of the magazine.

You can see more of those, including many by members of the PCO, which runs The Bloghorn, when the famously anti-establishment magazine puts on a First 50 Years exhibition at the very establishment Victoria and Albert Museum [Shurely shome mishtake? – Ed]. It opens at the V&A on October 18 and runs until January 8.

Cartoons will be shown in themed sections, on politics, royalty and social observation, and there will be gags, long-running strips and caricatures. The Bloghorn will have more on the exhibition nearer the time.

Ian Hislop, Editor of the magazine, has said of the 50th anniversary: “I do not want anyone to think that this is all just a huge celebration of ourselves. Our 50th year is a chance to look back and take a dispassionate view of how marvellous we are.”

You can read more on how marvellous they are in a Media Guardian article this week and even Vanity Fair is on the case with a piece by Christopher Hitchens. Updates on the 50th anniversary celebrations will appear on the Private Eye at 50 blog.
