Handwritten caption on reverse: '3 FG, 12 AF.' It is more likely the aircraft was assigned to the 3rd Photo Reconnaissance Group, since there was no "3 FG (Fighter Group)." It is difficult to tell the full aircraft serial, but the presence of the 'last three' (194) on the vertical fin is additional evidence that it is likely a recon unit, since this was a highly common ID method; none of the 12th AF fighter units claimed similar markings.
