Hoodoo practitioners, as well as the general public, found supplies in so-called Curio Catalogues during the mid-1900s. Since none of the potions, spells, talismans, mojo bags, candles, powders, and herbs could be officially sold by advertising what they were used for in hoodoo, they were sold as curios. Let us say, just-for-fun curiosities.
These are a good source for people studying hoodoo history because the advertisements in the calatogues provide spells and product names you can further look up in books and online sites.
You can find examples of these catalogues online at sites like The Church of Good Luck, Lucky Mojo Curio Company (which has a section about hoodoo itself), and by searching under the names of the catalogues themselves, the most widely known being the King Curio Company and the de Laurence Company catalogues. You’ll find examples from the 1930s and 1940s.
