This particular label design variant was in use since c. January - February 1946 (at which point Victor was officially renamed as RCA Victor), with appropriate subvariants for each pressing plant (closed rings for Indianapolis, open on top for Hollywood, etc.). The Hollywood {Images #881406 & 881408} was typeset by Bert-Co of Los Angeles which had done label typesetting for RCA Victor beginning in 1949 after that plant reopened later that year following a brief lull as a result of a sales slump that was exacerbated by the infamous "Battle of the Speeds." Apparently that printer used the glossy paper vs. the dull-coated Indianapolis {Images #435860 & 435861}. Would Bert-Co have used the standard 3" label size, or would they have shaved 1/16" off to 2.9375"? I know Indianapolis at this point was still using 3" labels. (It wasn't actually gray, just a very dull black. If you've seen Pantone swatches of coated vs. uncoated, you'll see the black about as grayish as the Indianapolis labels.) It was also around this period that Hollywood began pressing 45's, with a difference in the rim print above from Indianapolis pressings (an equal sign = placed between "Reg. U.S. Pat. Off" and "Marcas Registradas," vs. Indianapolis' positioning it between "RCA Monogram" and "Dog and Phonograph"); in fact the 47-5095 release of "Hot Toddy" was among the first such pressings, though that label variant (which also used dull black paper, though Bert-Co fonts were likewise used) isn't up on 45cat yet.
The "Color Nipper" labels would have been introduced in May of 1954 or thereabouts; I've characterized them as "Papa Nipper" for LP labels, "Mama Nipper" for 78 labels, and "Baby Nipper" for 45 labels. At that point RCA reverted to the older 2.9375" size that they used up to 1946 (after which they joined the other labels in using 3").
Added older-style label variant (black glossy label with serif font and Hollywood plant rings that are open on top).
55bluesman's label has closed rings (Indianapolis plant) and has the gray matte color of labels that were used between 1951 and 1953 when RCA Victor introduced the new Color Nipper label (Michael W. Sherman et al., The Collector's Guide to Victor Records, Dallas, TX, 1992, p. 77-78).
Since this record was not even released before Dec. 1952, the Hollywood plant must have used the older-style label much longer than 1951.
