Grosset & Dunlap
The Hidden StaircaseGrosset & Dunlap is identified in The Hidden Staircase’s front matter as its publisher. The surviving publication details connect the organization to the book through its imprint and copyright notice, but provide no broader account of the publisher’s history or operations.
Imprint and Copyright
The book’s front matter lists New York and Grosset & Dunlap as publisher, then gives a copyright notice dated 1930 in the publisher’s name. The notice establishes the year and the publisher’s stated copyright connection to this edition; it does not, by itself, specify a publication date.
Illustrated Edition
The front matter credits Russell H. Tandy as the illustrator and identifies a frontispiece for The Hidden Staircase on page 96. These details place Grosset & Dunlap’s publisher credit within an edition presented with an illustrated feature, though the available evidence does not describe the publisher’s production process or its relationship with the illustrator.
