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 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
