My first post and it dumped it, shoot. Okay, here I go again, hope I don't get timed out (newbie)- pics of my old french mustard jar, quite large, is about 6 inches high and about 3-1/2 for 4 inches across. The glaze is crazed and crackled and it looks really old. I've had it for over 20 years and can't remember where I got it, but I'm guessing a swap meet. On the front is says Moutard d'antan au vinaigre fin FAUCHON PARIS. On the bottom is says ceramique belgium with a rf in the middle (very faint impression only). Look at my pics. I cannot figure out the approximate value, could never find one listed anywhere. Any ideas of how to find out or anyone have expertise here? Thanks!!
