All Aboard the DC-7B

 

Nothing written on this slide, but it's easy to tell that this is a Douglas DC-7 aircraft. 

The DC-7B variant was the first long-range variant with higher gross weight and fuel capacity, with most of the added fuel in saddle tanks in enlarged engine nacelles

The mention of  Falcon Super Coach marks this as one for Eastern Air Lines.

Another slide shows this aircraft has the registration N848D, which helps. It later crashed in 1992, while serving as a water-bomber.

Bonus - Oh Dear. RIP Kitten Natividad.

Kitten featured in the film "Up".  No, the Russ Meyer one, not the Disney one.
