D7:
1927. Print. Black, orange and green. 17x19 and 24x28mm
Possible additional text: 'HANDPAINTED' or 'HANDPAINTED DESIGNED BY SUSIE COOPER' plus two wavy lines.
This represents the first general use of Susie Cooper's name as designer on a Gray's backstamp. Note that this mark is subtly different from the design of all other D marks: compare the liner's masts and the green waves of the sea.
