A scarce piece of mid-twentieth-century Scientology promotional ephemera: a cream-colored bookmark printed with L. Ron Hubbard's "Tone Scale," the foundational emotional/psychological chart central to Scientology theory and practice. The scale descends from 4.0 (Enthusiasm) through 0.0 (Death), with intermediate emotional states graded on a numerical scale.

This particular copy is hand-inscribed in blue ink: "Phone / N.R Brown / Scientologist," suggesting it belonged to or was distributed by a Scientology member or recruiter named N.R. Brown. The verso features the address of the Scientology Center, Albany, 899 Mercer Street, Albany 8, New York—a crucial detail for understanding the early organizational footprint of the Church of Scientology on the East Coast.

The reverse of the bookmark advertises Scientology books, correspondence courses, and membership. Prices listed include: Scientology: 8-80, Scientology in Contribution to Knowledge, and membership enrollment information. A membership card is offered for $15.00, with "20% Book and Tape discount" promised. The card directs interested parties to the Scientology U.S.: 1812 19th Street, N.W., Washington, D.C., or HASI, 37 Fitzroy Street, London (W.1), United Kingdom.
