The Morning Telegraph

The Morning Telegraph was a New York City broadsheet newspaper owned by Moe Annenberg's Cecelia Corporation. It was first published as the Sunday [Mercury (New York)|Sunday Mercury] from 1839 to 1897 and became The Morning Telegraph in December, 1897.
The paper was devoted mostly to theatrical and horse racing news. It published a Sunday edition as the Sunday Telegraph. On closing, it was replaced by an Eastern edition of Triangle's sister publication, the Daily Racing Form.
Observation: It isn't clear what the paper was called on Sundays. The New York Public Library website displays an article in a page headed "THE MORNING TELEGRAPH, SUNDAY, NOVEMBER 21, 1926" - see https://digitalcollections.nypl.org/items/322482e0-c608-012f-625e-58d385a7bc34
