This wildcard set is made for Vintage Labels: Ephemera Alchemica, but it can work with any vintage-looking LoRA made for Flux.

This simple file generates a series of wildcards that reproduce a vintage label. The features are random, but you can use the template to make any label you may want. Just download the file, unzip it, and put the yaml file in your wildcards directory. All you need to put in your prompt box is "__label-maker__" and it'll construct the prompt for you. You will need the dynamic prompts extension for it to work.

You can edit the nested YAML file to add more variables and get even more varied prompts.
