I didn't realise that such things were in the American vocabulary.
Arf.
Seriously, though, I think it's fine. Even if the Princess trick is well-known, it's well-known is a groovy to an eight-year-old way - 'This is a trick that David Blaine did.' It'll probably make them feel special; it's not at all being palmed off (excuse any pun aspect) with a 'kiddie trick'. And the self-promotion will quite probably been seen in the same way. I feel awful and self-conscious and embarrassed when I sign books, but I love to have signed books from other authors. Moreover, when an author visited my eldest's school the other week and sold sign copies of his novel, Eldest didn't think, 'Pah - he's coining it in.' He thought, 'Coo. I've met the author and got a signed copy of his book.' They'll be very happy about it, I'm sure.
