I have 25,000 images like pic related. Old timey engraved images. I found them in old books from Internet Archive before it went belly up. I cleaned them, vectorized them, converted them to backgroundless PNGs. Where can I sell them? I'm trying to get 250 - 300 USofA dollarinos a month. Etsy? What image service should use? Do they even exist anymore?

Also, you have a freebie in pic related.
