Rudolph's second Christmas

Although the advertising asserts that May's daughter discovered this "lost" manuscript, May had in fact published the story in 1948 but NOT IN BOOK FORM!!! I own the RCA Victor 2-record 78rpm gatefold set Y-441 in the Little Nipper children's series. Rudolph's Second Christmas as told by Paul Wing Story by Roberyt L. May "A New Adventure Of Rudolph the Red-Nosed Reindeer". This is the only copy I've ever seen, so the record must NOT have seen wide distribution.
