Based on the 1951 recording dates associated with nearby cat. nr.s (compare, for example, Esquire 183, recorded July 12, 1951, on http://henrybebop.co.uk/esquir78.htm), I'd say 1951 is the likeliest year of release.
Esquire wasn't started until '47, so the date of '46 on this is wrong. This cat#'s place in the sequence suggests '51 or '52. I've taken the year out altogether until we have firmer info.
