Radio Free Albemuth

A Science Fiction Book Club hardcover followed in 1986 using the same Walotsky jacket art, and it is routinely miscatalogued online as "Arbor House 1985" — this is the main trap. Tells: no Arbor House number line on the copyright page, no price at the jacket front flap, a blind-stamped device at the rear board, and a smaller, lighter bulk. The Avon paperback (1987) and Vintage trade paperback (1998) are plainly imprinted reprints.
