Welcome to the board, Jimbo.
There are already 20 books of Beau Peep strips published, which I am sure you already know, most of which can be bought second-hand from Ebay. If by 'annual' you mean a yearly or even one-off book about Beau Peep to be sold in shops, personally I can't see that either happening or selling, not because Beau Peep isn't good but because I can't see enough people buying it.
But I may be wrong. Indeed, I'd love you to prove me wrong. There's a guy on this board called Rob Baker who has all the Beau Peep strips, and I once had the idea to scan the whole lot and put them online.
Exactly what do you think ought to go into these annuals?
