French newspaper label to Mexico with 1/2 medio in 1868 ?

[Jean-Claude]

Hello Manuel, Thanks for your response but my responses may not satisfy you : 1. there is no half mark known in France at any time; the newspaper rate in France was 1 centime, there has never been a half centime for anything in France, whilst there was for Mexico with the half real from 1856 until its replacement by the 7centavos Maximilian reduced to 6 centavos with the 1868 issue. 2. newspaper was named "Le Gaulois" as indicated on the label and was avery famous Parisian newspaper. Le label was taken off the paper too voluminous probably. So not much progress I am afraid ! Thanks anyway for your input.

Jean-Claude,
Pardon my ignorance but: 1. How do you know that the the 1/2 Postmark is of Mexican origin and 2. Where is the newspaper?.The answer in my opinion is NO.
Best regards,
Manuel.

I am looking for help to a French printed matters collector who bought the attached label attached to a newspaper sent to Mexico in 1868. On the label a 1/2 black mark is apposed next to the French newspaper hand-stamp dated in 1868. At that time the centavos had replaced the medio real. Circulars were taxed 6 centavos then. There is no 1/2 mark quoted at Veracruz in the Taylor catalog; the only close 1/2 is at Mexico but for 1856 only and carries a 40 !So, can we confirm the 1/2 applied as a genuine Mexican mark as medio ?Thanks in advance.
