Everything leaves a trace. That's been my guiding principle researching the history of early wargames and role-playing games: any commercial product that survives, no matter how obscure, had to be available somewhere and somehow, and that means a paper trail. All too often the products themselves give us little indication of when they were made, as was the case with today's subject, Monsters! Monsters! Monsters! Galore. But with the help of distributor catalogs, we can show how it became available in 1980.
