The message on this post card says “Just to let you know what sort of a place this is like. Jack” It was sent to Miss D Clark (no address given) and someone has added the date 12/2/17.
The post card was produced by S. Osler P.O. Forest Town. Shadrach Osler was the Post Master and his name can be seen over the middle shop on the left of the photo which at that time was the Post Office.
The soldiers would be walking from Clipstone Camp into Forest Town and possibly on to Mansfield.
