I would like to hear from you guys which are your favorite titles from this great collection. At the present I onw some of them, some great, some not so much. Spad VII Acesfrom Jon Guttman and Aces of Jagdstaffel 17 from Gren van Wyngarden are amongst my favourites.

Alb DIII Aces is the only one I currently have but it is fun book - meaning that it is a entertaining read.
Someday I will get the whole series just because of my positive feelings for the series based on this one.

x2 on that. I like it. It's good reading and easy as well. I also have a few books by Norman Franks which are fantastic, but definitely not with a glass of wine (or favorite high ball).

I have 6 Osprey books of WW I aircraft, I use them for scale documentation. All are a very good read. Here are the titles: Fokker D VII Aces part 1&2, SPAD VII Aces, SPAD XII/XIII Aces, Fokker Dr I Aces and Richthofen's Circus'. I always pickup at least one new book when I go to the USAF Musiem at Dayton Ohio.

Dayton?
Did you ever go to the WW1 Dawn Patrol fly-in?
I live about 3 hours away.

Same here; it's the only one I have yet. It is a great, easy read even for Germans,
and it contains plenty of photos and very good colour profiles.

This one you mean guys?

I have all of Ospreys WWI titles... Some great illustrations for skinners, brief unit histories, aces stories on combat and patrols, also many are written by respected authors
