Each Spider novel contained 8-9 large illustrations per issue when first published (as well as many "spot" illustrations). This always included a two-page opening spread, a large portrait each of Dick and Nita, and a montage of the novel's guest cast; The remainder depicted the principal action scenes in one or two pages each. The first 109 of 118 Spider tales were illustrated by J. Fleming Gould who was also the artist behind Operator #5 and G-8 and His Battle Aces. That's well over 1,000 pages of illustrations for The Spider alone! Gould estimated that he did in the neighborhood of 15,000 Pulp illustrations from 1927-1942. Unfortunately few original pieces survive; His artwork was normally returned to him and he admits, ruefully, that he either threw these out or burned them.
