All 5 biscuits are included in this one lot

There is as to be expected age related wear to these. One has a couple of seams coming apart. I have taken close-up photographs of these as they shows the original internal filling which looks to be straw. 

My understanding is that 3 of these would've been used to make up one full bed.

Each one is approx 3ft Square

As can hopefully be seen on the photograph one of the biscuits has a broad arrow stamp and is dated 1942. 

I cannot see any other stamps/markings on the other biscuits.
