Even though the name of these plywood, and most certainly veneer, importers does not appear on this ghost sign, it can be identified as being that of Reuben Bros. I have not found when this firm was founded but it may not have been before the 1910s as, according to
Chambers Dictionary of Etymology, the word 'plywood' was first recorded in 1907.
The firm originally consisted of a partnership between two Reuben brothers but on 31 December 1937, The London Gazette published the following notice:
NOTICE is hereby given that the Partnership heretofore subsisting between us, the undersigned Hyman Reuben of 72 The Avenue Brondesbury London N.W. and Julius Joseph Reuben of 226 Watford Way Hendon Middlesex carrying on business as Plywood and Veneer Importers, at 390 Hackney Road London, E.2, under the style or firm of REUBEN BROS, has been dissolved by mutual consent as from the 24th day of December 1937-—Dated this 28th day of December 1937.
HYMAN REUBEN.
JULIUS JOSEPH REUBEN.

Even though the partnership between the Reuben brothers came to an end in 1937, Hyman Reuben continued trading under the name Reuben Bros at 390, Hackney Road for 14 more years. As for his brother Julius Joseph Reuben, he set up a limited company with addresses at 311, Euston Road and 66, Warren Street. Other members of the family also became plywood merchants, trading from a variety of addresses in central London and Hackney according to various editions of The Timber Trades Journal and Saw-mill Advertiser from the 1940s and early 1950s.
However in late 1950 or early 1951 Hyman Reuben presented a petition for the winding up of Reuben Bros. It was heard at the Royal Courts of Justice on 14 January 1951. A few months later, S. Fisher Ltd, radio and television cabinets maker moved into the premises.

There is something curious about this ghost sign. Indeed, why were the upper and lower parts left intact when the central part, which certainly featured the word "veneer", was painted over?
