I have the Coronet 78 as well as the 45
Strawberry Lynn, mickey rat is right, a few "later" octagonals had a black border just prior to the round label, interesting to note that most of not all 10" LPs had the border, the 78s certainly didn't and it was a mixed bag for the 12' LP
This 45 was released as LL 37 in 1957, but this CBS label is maybe 2nd pressing of the 60's. I suppose that the 45 was released on Columbia label originally. In the 1950's, 2 artists on one disc is not uncommon in Japan.
