The parade took place on Feb 26th & the drawing was done on the 27th. The year date is obscured by the edge of the frame, so anywhere from 1915-1918. Basically the written narative says it was a Royal Artillery parade being inspected by  ROSA  No idea who ROSA was, obviously someone of great importance as is states  “Never since its formation has greater honour been known.” Signed by    Drawn by our tame artist    Overall framed size 28cms x 20.3cms, image size 24cms x 16.5cms. A cracking WW1 collectable.
