I'd like to see a form-fillable prop that has the bones of an auction catalogue as the core and a series of fillable fields for an auction title, auction house, location and the various items being sold. There are several official scenarios that either use an auction as a hook or have an auction as a way to acquire artefacts. I'd love to have something as a handout that looked the part. Ideally one for the Gaslight period and one for the 20's would be great but I have little skill with the operation of an appropriate application and can only hope someone put's such an item out in the wild.
I know that there are already a number of template sites about that have various pre-made options but they tend to be far to modern in design and nothing I've already spotted really matches the tone of a 1920's auction for antiquities or musty tomes.
