c. 1907 (based on Metro Postcard entry for the Excelsior Fine Art Publishing Co.)
On the back:
“At New Orleans, the world’s greatest banana port, more than 700 ships arrive each year loaded, each with 25,000 to 50,000 bunches of this popular fruit. At the banana wharves the individual bunch is carried from the hold of the ship to the door of the refrigerator car on mechanical conveyors.”
Published by New Orleans News Co. Can’t narrow the date, but 1920-1950
A series of postcards of the Royal Mint.
Undated. (However, a card from a different series showing one of the same images is postmarked 1939. See bottom of post.)
“Gold Melting House. The Royal Mint.”
The is the same picture as the previous image, although of a different format (BW with a white border & a poorer quality image when scanned in). It is postmarked 12 July 1939.
Series of postcards of “Cunard White Star R.M.S. ‘Aquitania'”.
Cards are undated by the company name “Cunard White Star” was in use from 1934-1949. They are most likely pre-World War II, as the ship was put to other uses after the start of the war, so 1930-39 seems a likely date.
