From Wiklipedia:  The 1914–15 Star was instituted in December 1918 and was awarded to officers and men of British and Imperial forces who served against the Central European Powers in any theatre of the Great War between 5 August 1914 and 31 December 1915. Like the 1914 Star, the 1914–15 Star was never awarded singly and recipients of this medal were also awarded the British War Medal and Victory Medal, but only one of the two Stars could be awarded to the same person. The three medals were sometimes irreverently referred to as Pip, Squeak and Wilfred after three comic strip characters, a dog, a penguin and a rabbit, that were popular in the immediate post-war era. Pip represented either of the two Stars, Squeak represented the British War Medal and Wilfred represented the Victory Medal.
