'Sea Horses'

Issued Sep to Dec 1915. Designed by Bertram Mackennel and printed by De La Rue on 'Simple Cypher' watermark paper and perf 11 x 12.

These earlier Waterlow and De La Rue printings are exactly 22.1mm high. The later Bradbury Wilkinson printings are 22.6 to 23.1mm high due to the curved plates used in printing. On most of the later stamps there is a minute coloured guide spot in the margin just above the middle of the upper frame line.
