The colours of the fuselage bands are white and black. The machine is a Alb. D.V from Jasta Boelcke. The figures are Bassenge, Kempf and Vallendor. The three are (L to R) Gerhard Bassenge, Fritz Kempf and Hermann Vallendor (incidentally, all hailed from Baden). The D.V in the background was almost certainly striped in black and white. Yes, it did have a white tail unit but additional chordwise black stripes were applied to the tailplane. The machine probably belonged to Kempf.
1.Ltn. Gerhard Bassenge joined Jasta "B" on 2 May 1917. Was WIA on 6 Nov.1917. returned to duty on an unknown date.
2. Ltn. Friedrich Paul Kempf joined Jasta"B" on 4 April 1917 to 17 October 1917 to Jastaschule, return to Jasta "B" in January 1918.
3. Ltn Herman Vallendor joined Jasta"B" on 24 August 1917 to the EOW.
4. Jasta "B" had the Alb.D.V by 14 September 1917
and began receivng the Fok.DR.I by 14 January.
The earliest possible date was 24 August 1917 when Vallendor joined Jasta "B",another factor was earliest possible date was 14 September 1917 when they had the Alb.D.V on strength. The latest possible date was 17 October 1917 when Kempf went off to Jastaschule. So,this photo was taken between 14 September to 17 October 1917. The Location on 14 September was Varsenaere Airfield to 30 September 1917 and Jasta "B" moved to Rumbeke Aifield on 1 October and were there to 12 November 1917. Both airfields had sheds so it becomes a choice, my guess is Varsenaere Airfield, bright sunlight, strong shadows, sun still high. However it could be Rumbeke.
I picked up this same poster in 1973 at the Balboa Park aviation museum in San Diego before it burned down a year later. Though it was rebuilt it was such a tragedy. Below is another fellow's framed poster.
