Mueller and Feist, with a Pfalz and... a Teddy Bear?
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.
