A pair of RAF Photographic Printing Blocks

We believe these date from WWII, deduced by the uniforms worn but also both appear to be dated 1943 on the reverse. One block features a photographic image etched on a copper plate showing an RAF man relaxing off duty with pipe in hand, who is wearing Khaki Drill shorts, long socks and an RAF Battledress blouse. No rank or other badges are shown so it is impossible to identify who, where or exactly when. The other block, which is of identical dimensions 4.25"x3.00" (11 cm x 7.5 cm) and the etching features an RAF sergeant standing in his No 1 Other Ranks uniform without cap and with hands in pockets. Sadly the paper label to the reverse is in poor condition but also appears to be dated 1943 as mentioned already and also an indistinct name which we have been unable to decipher. Printing blocks like these were used alongside similar blocks containing typescript and were mounted in a printing press to commercially produce images and text for publications and it seems likely both images may have been printed in the same unknown wartime article. The copper etchings are nailed to a mahogany hardwood block and these represent a modestly priced and unusual pair for an RAF or printing collection that illustrates a technology that is now just for the history books.
