Update to previous post. From The London Illustrated News of 18 August 1849:
EXTRAORDINARY BARGAINS, until SEPT. 25th, at DISON’S, Her Majesty’s Laceman; when the shop POSITIVELY CLOSES. The lease being disposed of, it passes into another business. Twenty-seven years of Dison’s occupation of them is enough to guarantee the superiority of the articles left on hand, from which an immense reduction has been made. N.B. No. 237, Regent Street.
