Jaudel was successor to E Legrand (qv). In the i920s Jaudel had a succession of one-line entries in Bottin at 93 rue Montmartre. J Petitjean who previously had been in partnership with Lochard producing cards with marques LÉO, BLEUET and DÉDÉ (qv) seems as Director to have reactivated the company.
In 1930 he is producing cards with marques CARMEN, LIDO and J.P.
The marque J.P. had recently belonged to J. Picot, Paris
and it is possible that JP cards shown there were actually produced by Jaudel.
