Lithographic printing and publishing firm run by François Séraphin Delpech (1778-1825).

From British Museum website:
Lithographic printing and publishing firm, set up by François Séraphin Delpech (1778-1825) in 1818 (the authorisation to set up his own press was given on 16 June 1818). After his death the business was continued by his widow, who signed as veuve Delpech from 1825. Closure date not yet ascertained.
He issued various 'Albums Lithographiques' between 1819 and 1825 with prints by different artists: these are very rare. The front of the shop is shown in an 1820 lithograph by Carle Vernet.
