I sell public domain art prints on Etsy. Haven’t done anything on it beyond fulfilling orders for years - I found a really high-quality printers who do the production and shipping - but it’s probably good for an extra £100-300 a month, depending on how Etsy’s algorithm is feeling at the time. I could probably sell more if I put more effort into it, but it’s nice as a very low-effort, if small, income stream.
