Gresham Ghost

One of several entrance/delivery door ghost signs in Bradford's Little Germany district, this one shows at least two generations of signage for HF Gresham & Co., together with some ornate iron work which is typical of the warehouses in this area.

All I've managed to discover discovered about HF Gresham & Co. so far is that they were wound up in 1960 (thank you the ever reliable London Gazette), and that they were represented in Colombia by Alberto Arango Trujillo (thank you obscure Colombian trade directory).

Update: Mrs S suggested I checked the trade directories. Good advice as I found an advertisement for Gresham, Blundell & Co. Ltd, trading from the address for this sign, in the 1917 Kelly's Directory.
