Paulette Rollin ‎– Chants De Noël

Hi,

Could someone help me find the release year of this (these) album(s) as I presume they are the same (one released under Mercury Records, one released under Barclay Records) :

Here's another source dating it from the fifties:

This release with a different sleeve is said to have been released in 1960 but it may be a reissue :

On this source that same album is dated 1954 :

And by the way could someone confirm that a "33 standard" is a 12" album and a "33 medium" is a 10" album ?

Thanks for your help !

I would guess that 1954 is the correct year given how common 10" LPs were in the early 1950s.
