again with the reply to your id, not the list!

"Mary Roberts Rinehart
Rinehart wrote hundreds of short stories, poems, travelogues
and articles.  Many of her books and plays were adapted for
movies, such as THE BAT(1926), THE BAT WHISPERS(1930), and
THE BAT(1959 remake).  In 1933 RCA Victor released THE BAT as
one of the earliest talking book recordings."

I found something interesting today.This is an eighteen page hardbound book,published by David McKay,of selections from "A Child's
Garden of Verses".It is ten inches square,and illustrated by H.Willebeek le Mair.What makes it interesting is,it says it's a
"talking book",published by The Talking Book Company of New York.It came with a record of the poems,with original music written by
Helen Meyers,and sung by Josephine Therese.I can find out nothing about these women.The record was made by RCA,who placed their
logo on the cover.The book has two copyright dates,of 1926,and 1940.Is it a 1940 reissue of a 1926 record? I can find nothing
about the company,but there is one of these up for sale on AbeBooks,and like my copy,it has no record.There is also reference to a
"Little Black Sambo",in the same series owned by the Library of Congress.   This was all I could find.What I was wondering,was could
 this somehow be a successor to the Talking Book Corporation,who made those records on cards,with Emerson?Are there more of these
1940 records in Peter Muldavin's book?
