Neat New Stampless Cover From Tonight.

I'm not that good with Ship letters, but this is what I'd say it was:
The black squiggle on the backflap is the French payment - 9 decimes paid for French postage and transatlantic carriage.
PP is French and designates that it was paid to the border (it would be stamped "PD" for paid to destination).
It was handed to a non-contract steamer in Harve by the forwarding agent(AG Smith oval handstamp.
(There were no ships carrying mail under contract to the government to carry mail between Harve and NY until 1850)
Entered the mail in NY as a ship letter - 2 cents for the ship letter and 10 cents for postage for a total of 12 cents due to a destination beyond the port city.
The NY SHIP 12 is listed as being used from 1847-48, which would make it likely 1848 (the year date would be under the "1" of the "12"

Hope that helps.
Chip

This may help date the cover to before 1848:

Chip & wt1 I am very pleased to have that information. for a few hours last evening I have been scouring the internet for the ship Burgundy, but have had no luck. The marking I got a little insight on but nothing like what you guys posted. Thank you.
