December, 1953 is Marv Goldberg's guess, based on the fact that the recordings were mentioned in "Records Released This Week", in Jan. 9. 1954 Billboard. Seems reasonable, but it doesn't fit well with the release date of Gem 211, which was August of 1953 according to Ferdie Gonzalez. Likely one of the two dates is incorrect, and with the date here being corroborated via a trade paper, I'd guess that Gem 211 actually didn't come out until 1954.
