Delicate, almost transparent in the light, blue opaline glass lidded jar. No pontil scar, marked inside with what looks like the number 49 in gold paint. Please see all pics; there is some wear to the gold on the lid, and it looks like at one time the lid was taped to the jar, to protect it, but there is some residue that I have no tried to clean because of the delicacy of the piece. Probably French instead of Moser, but I’m not certain.
