Diary: Top guns to save adworld with a flash of their biros

Autograph hunters don't come more persistent and tenacious than the IPA's Pamela Perl.

And tonight (Thursday) sees the climax of her efforts when a special copy of Campaign's Hall of Fame goes under the hammer at the Nabs Big Bash fundraiser.

Of the 40 Hall of Famers, all 30 that are still alive have each signed two copies. One is to go under the hammer for Nabs, the other is to be sold on eBay to raise money for the History of Advertising Trust.

For Perl, the executive assistant to the IPA's director-general, Hamish Pringle, the past four months have seen a steady stream of famous faces dropping in to sign.

Ray Morgan, Ronnie Kirkwood and John Perriss all obliged as did the one-time hell-raising creative Alan Waldie. "He was lovely," a bedazzled Perl says. "And such a fund of anecdotes."

Even the most potentially elusive joined in when Charles Saatchi promptly returned the copies biked over to him - although they were signed merely "X".

No such reticence from brother Maurice who signed his entry with a flourish "Saatchi".

Perl, a self-confessed Antiques Roadshow addict and a bit of an expert herself when it comes to the collectibles market, reckons she knows how much the copies will fetch - but she's keeping the figure completely under wraps.
