Vol. XXVI, No. 1
The issue frontispiece happens to illustrate the Kipling story listed here. (The issues of volume 26 differ in that respect.)
Its
front cover (both sides) is the frontispiece of volume 26 as bound, in that copy from U Michigan at HathiTrust Digital Library.
The Kipling story, pp. 23-35, begins under this 5-line heading, in three sizes and fonts (all caps, centered over two columns):
With the Night Mail*
By
Rudyard Kipling
Illustrated by H. Reuterdahl
(McClure's Magazine Advg. Dept., June, 2025 A.D.)
where * refers to a footnote statement of Kipling's copyright.
Illustrations.
Two b/w illustrations, full-page and nearly so, are contained in the story as printed (pp. 29, 32). Another illustrates the penultimate paragraph of the story (p35). It is reproduced in color as the issue frontispiece, presumably; it faces p[1] in bound volume 26 viewed at HathiTrust --two copies, from U Michigan and Cornell U.
