The sets were housed in a hard case (actually a pre-existing design normally used in Armoured Fighting Vehicles for carrying War Office maps of the UK), and whilst the maps covered identical areas to regular GSGS mapping sheets, the maps themselves are not 'standard issue'. They have been specially produced with a glossy coating similar to that used for the RAF's 'FOLDEX' system map sets. (The 'FOLDEX' covers state that this surface can be written on in 'chinagraph' pencils and then rubbed out with a normal eraser so that they could be used repeatedly for plotting different flightpaths etc.) Whether the special coating on the tank maps is for the same purpose is not clear, but they are definitely unlike all other British Army maps.

They were also produced without the usual marginal information (perhaps due to their intended use in a confined space), although some of them retain portions of the original standard sheet margins, but for absolute clarity, this is exactly how they were issued. Therefore, to aid storage, identification and retrieval from the case, each map had a glossy linen backed tab indicating the relevant sheet number and GSGS Series number. These could be cross-referenced with the index cards stored in the lid of the case, which also contained the information normally included in the margins, such as keys of 'CONVENTIONAL SIGNS' and 'GRID SYSTEMS' etc.

Under normal production circumstances, this sheet would have been headed "ORLEANS", and it features the Southern flank of the NORMANDY BREAKOUT, including the city of LE MANS.

It's in very good condition, with a single handwritten annotation relating to the area covered (see photos).
