Yes, it is a concern, but since the bottle is shown in black and white and much of the main label is obscured, I didn’t try to resolve my doubts. It is hard to be certain, but it looks like that bottle may also have the language “Mis en bouteilles au Domaine” incorrectly aligned like the 1945. I would also have to find some 1955s with documented provenance to compare.
Must say that the catalogue seems to try to hide as many of the labels/capsules as possible on the older bottles, almost as though they are deliberately aware of not wanting them under close scrutiny.
Believe The White Club was/is a wine club that would organize dinners with some very high end/rare wines. Now imagine selling a dinner serving these wines and the bottles being refilled with plonk. Could not find the link in here for the stories.
