There was a play–I suppose it was a children’s play and I don’t remember the name of it or the author–but the central character was named Mr. Tell-Us-A-Story-Man. I played that character in at least two different productions of the play–at school and at Sunday School when I was in the 3rd and 4th grades–so when I was 9 and 10 years old. I wish I could find that play–google-searching has been no help. I can see the text of the play in its published form, printed on cheap already yellowing paper.

New format, same book stumper solving.
A character of the same name is in “When Toys come to Life”, a children’s operetta, which seems to have been performed also as a play.
There was a score, by Theodosia Paynter and Lucille Hathaway (Amazon has a picture of the cover and title page), and the interior does look to be yellowed paper.
