Note squadron insignia on far right side of nose. (Link)

This insignia was used by a different squadron prior to its approval for use by VP-61. It continued in use following VP-61’s redesignation to VJ-61, VAP-61 and then VCP-61.

The squadron’s first insignia was approved by CNO on 2 October 1951. This insignia had been used by VC-61 before being approved for use by VP-61. Colors for the insignia were: a blue background; a gray and white goose with a pink foot, green eyes, yellow bill, and a red tongue; the pilot and gunner’s uniforms were olive green with yellow life jackets, pink faces, brown gloves, boots were olive green and brown, red nose and green eyes; black and white pilot’s helmet and red gunner’s helmet; black gun with white highlights and a brown stock; gray camera with white sides, a black and white lens with a blue and white sight; the globe had blue water, yellow and white land areas and black longitude and latitude lines.

Those men are wearing sailors' hats, and the aircraft is in dark (probably blue) paint, so evidently this is a Navy aircraft. The cockpit design is obviously a Liberator (B-24) variant. The Navy flew a few C-87 Liberator Express transports in WWII, but I bet this is the patrol version, built specifically for the Navy, the PB4Y-2 'Privateer'.
