Author: Fergus Hume
Year: 1895
Publisher: United States Book Co.
Pages: 453
Binding: unknown
Type: Novel
Title Reference: The Island of Fantasy
Notes:
HathiTrust Digital Library provides full view of one copy without original cover: Title page displays "United States Book Company", no date; t.p. verso states copyright 1892 by that publisher.

Publication date inferred from listings in "Books Received", Det. Free Press 1895-07-15 p3, and "New Novels", Phi. Inquirer -07-20 p7 (no price). There is a listing in "New Books Received", Was. Post -07-22 p7, as "... New York: The United States Book Company. Washington: Woodward & Lothrop. Paper, 50 cents." Evidently from the entire column, Woodward & Lothrop is a retailer with a Washington location.
