Another vote for Trudgian here.
I also have a couple of Ronald Wong prints, he did alot of stuff for squadrons of the USAFE including the well known ‘Dover Patrol’ depicting a couple of F-15E’s off the Dover coast.
Mark Postlethwaite,Robert Taylor and Geoff Nutkins are other favourites.

Wade Meyers has done some fantastic paintings and pencil drawings of the 4th FG aircraft as has Troy White, although the latter’s works can be a bit hit and miss (more hits) in my opinion.
