Dennis Gray’s contribution is a compilation of photographs taken by his Uncle, Bill Gray (circa 1935-41),
his father, Charles Gray (circa 1940-41), and himself during 1969-73.
It is a wonderful collection of aviation history in PNG,
combined with a cross section depicting living in PNG during these periods.
(Sponsor’s comment : These are exactly the pictorial archives that we are seeking before it is too late:
so ..have you PNG slides/photos of historical interest languishing in the bottom drawer ? )
