The info which came with this photo says that the two fellas are 'Leutnants Mueller und Feist mit ein Pfalz D.IIIa'. Ich kenne nicht... uhhh... I mean, I dunno if that's correct or not... I'm just the messenger here. However, it does look like a Pfalz to me and I *do* know that the presence of a third member of whichever Jasta these guys were from is clear evidence that just about everyone has a sense of humor.
Your blogmeister feels it necessary to preface this first post with the following disclaimer... he is fascinated by the flying machines of the First World War, but knows relatively little about them compared to things with wings of other eras. So when there is accompanying information readily available, it will be included with each photo posted. However, more often than not, no great effort will be made to confirm or expound upon that information... the photos will quite often stand alone to speak for themselves.
So... here you go... three guys and an Albatros D.III. (I think)
