What Year Was The 'Legends' Gate Price £18.00?

I’m trying to date some books and models I bought at ‘Legends’ and all I’ve got is the ‘on-the-gate’ (because you could back then!) price of £18.00 to go on…

…it’d also be good to know how many ‘Legends’ I’ve done over the years and this was my first maybe?

Would have been pre-2005 and I probably didn’t pay with a credit card (so can’t check statements)!
