This logo is sometime ascribed to Levy, as it
appears on Levy fils cards,
for example LF Co 2051 shown here, surrounded by the Levy laurel leaves.
It does occur on other cards, eg the ELD card shown, but it is almost always too small to read the details. However the card
DAL 185 has the logo big enough to be seen properly, This card was
photographed and printed by D.A.Longuet, 250 Faubourg St Martin, Paris. It has the visé mark introduced in 1915
(see under the Visé logo entry).
Incidentally, the ELD card seems to violate the Visé regulations as it lacks a number.
