Hi Maveric,
This looks very much like a projected commercial version of the USAAF C-74 Globemaster (the prototype flew in 1945). The tail is very similar.

Yep, the Pan Am markings are the give-away (the Lockheed Constitution was also proposed to Pan Am).

"Douglas began discussions with Pan American World Airways in 1944 for sale of an airliner version of the C-74 for commercial service after the war. The "civilian" C-74 was to be designated the "DC-7", though Pan Am called it the "Clipper Type 9". Pan Am ordered 26 DC-7s in June 1944, but the price kept climbing and the order was cancelled in October 1945."

It seems this is a 'first' DC-7 shown here, which was to be a civil version of the C-74 Globemaster I. Later on the design was changed and the DC-7 that we all know appeared.

Dear Boys and Girls, here is another artist's impression of the Douglas DC-7 "project" of 1945 in Pan American World Airways Inc. livery; still with the C-74's individual bubble cockpit canopies......

Notional airliner design, or an early variation on the DC-7 theme? This is from a 1945-ish advertisement for "The Airlines of the United States", and it does look an awful lot like a Douglas design of that time.

Here's an interesting bit on the C-74 which shows the same cockpit arrangement that was meant to be used in the "DC-7."

Waaaay out of my league, but of possible interest to other members is this beautiful original company blueprint for the Douglas Model 415A, better known as the C-74 Globemaster...

Interesting in so far, as it still seems to differ from the first "bug-eyed" variant, at least to my eyes.
The cockpit canopies seems to be shallower, the fin more rounded and positions of the windows
different, too.
Question is, if those points really were changed during further development, or if we just have another
case of just an approximated general arrangement drawing, not quite unusual for the period and this
(and surely other) manufacturers.
