..bought my copy (still shrink-wrapped)a couple of years ago from
www.christian-schmidt.com for 24 Euros..first published 1988 Verlag Schütz, 350 pages, large format..it is an "umfangreiche und erschöpfende Bildchronik" (extensive and exhaustive pictorial history) according to the blurb..documenting the life and times in war and peace of the Immelmann Geschwader..the last 50 pages deal with the post-war AG 51 (Aufklärungsgeschwader RF-84, F104s, F4s )
Not much coverage of the Fw 190..or many 190s correctly identified come to that..
if you've got Nauroth's JG 2 book you'll know what to expect..I'm not unhappy with it, but of the 600+ photos I'd say less than 50% featured the Ju 87..
