An historic archive of 50,000 glass negatives has been cleaned-up to reveal rare images of London?s transport system that will go on show for the first time next month.

The precious images ? the earliest of which dates back to 1932 – have been uncovered after four years of preservation work undertaken by volunteers, made possible thanks to a £10,000 government grant.

They include a 1933 picture of an LT-type bus (pictured) and a 1934 photograph of the ?exhibition space? in the ticket hall of Charing Cross Underground Station – now Embankment.

Organisers say the images have never been displayed before and their unveiling coincides with the 150th anniversary of the London General Omnibus Company which takes place this year.

The volunteers ? who are all Friends of London?s Transport Museum ? cleaned the glass negatives and held them in temperature-controlled storage before digitising many of them.

The images are due to go on show on 20 and 21 May at the London Transport Museum?s Acton Depot, 118-120 Gunnersbury Lane, London W3 8BQ.

Entry will cost £6.95 for adults and £4.95 for concessions.
