Postage Due Marks On Stampless French Postcard Sent To UK

I was wondering if anyone here could interpret the following marks on the French postcard that was sent without a stamp. There is a T in a triangle, an FB or FOB, a large 3, a small 5 or g.

The postcard is a black and white pictorial showing a church.

Id something like this worth anything?

Here you have a 3p postage due with FB below (foreign Branch)in coming mail.The "T"(Tax)in this case is the UPU marking for postage due.

Attractive card. All the markings are there and clearly readable. I had not seen the "T" within the inverted triangle before.

Brilliant, thanks you to perf12 for that. ***Removed by Mod, no advertising until you have 50+ posts***. I love the way people used to write around the margins to get the most out of their communication!

Nice card.

I like the large "3D F.B." 3d postage due mark.

These are quite common but they are certainly collectable.

The small "O" below the F.B. (London Foreign Branch) appears to be just a handstamp identifier. Other letters exist.

SG gives a price for this postmark on cover of £2.00 in my 2011 Collect British Postmarks catalogue.

Thank you nigelc. Now I know everything about it!

As to your question about value, all postal history has value, including this card. Unfortunately this is nothing special so the value might be in the range of a cup of tea down at the pub. As has already been suggested, the "small 5 or g" as you put it is actually a letter D with a line under it. The letter D is the old currency symbol for pence which was replaced in with the letter P in the new decimal currency in 1971. It is interesting that the letter D for pence in the old currency system actually stood for the Latin word 'denarius' which was a coin of similar value to a penny during Roman times. You might want to look closely at the picture side of this postcard to see if there might once have been a French postage stamp placed there that has since fallen off. Placing the postage stamp on the photo side of a postcard was not entirely uncommon in those days. The T in the triangle which indicates postage due (the T stands for Taxe Perçue - the Universal Postal Union uses French terms) indicates that there either never was a postage stamp on the photo side or if there were that it had fallen off by the time it arrived at the British post office. This card would make a nice start for a collection of British postage due stamp use. Such a collection would be fun, interesting and of modest cost to undertake.

Under no circumstances should you consume tea in a pub

Another interesting thing about this card is the departure cancel 8 feb. "Valence Gare" (late afternoon); and arrival Paddington 9 feb (early evening). That is very fast service.Even with today's mail service it would be unlikely….

So right perf12! Fast service even with no stamp!
