The "Instant Handouts" is the first part of a role-playing game project that provides instantly usable game-enhancing supplements for every TTRP (and VTT) GM in 17 main categories.
The handout collection covers the period between 1900 and 1960, with pre-made high-resolution certificates, documents, and other elements. Some of the elements are historically accurate, but there are also some fabricated ones specifically created for role-playing game purposes.
