Spinner rack

A spinner rack is a rotating merchandise display, usually placed on a retailer's floor or counter. Often used to display magazines, paperbacks, greeting cards, postcards, hats, or seeds, the spinner rack is closely associated with the comic book industry.

A typical spinner rack is composed of a metal central spine with wire pockets, baskets, or pegs. A floor unit may have between four and twelve tiers (usually with four pockets on each tier) that may or may not rotate independently. Additional features may include a signholder that sits on top of the unit. (A typical comics spinner rack would have 44 pockets, with each pocket holding around five comics.)

Author George R. R. Martin, in writing about the spinner racks he knew as a child, notes that they offered a hodge-podge of titles (in his case paperbacks) regardless of genre, and thus exposed readers to a wide variety of writing, as opposed to the modern bookstore, where books are generally categorized by topic.
