Interesting WW1 Photo Postcard Yorkshire Regiment Boxing Team

This is an interesting photographic postcard showing a team of men from the 18th Yorkshire Regiment boxing team. At their feet you can see boxing gloves either side of a ball which says '3rd course'. On the back is written 'J. Garratt L/Sgt 18th Yorkshire Reg'. The card is in fair condition, one tear along the top edge and signs of wear.
