Pair River Thames wharf maps dated 1930

Rare linen backed wharf maps ,one dated 1930 the other a few years either side (undated) ,both published by Imray, Norie & Wilson, London The Minories, EC3.
They are probably for insurance purposes as they list all wharfs in the relevant map area .
There are numerous condition issues as I think fully conveyed in the images, but please ask if more detail / pics are required.
The first framed map shows 'Bekton & Vauxhall Bridge' and the other, 'Barking Creek to Hole Haven'.
