I was browsing Etsy the other day when I happened across these wonderful illustrations of “fanciful submarines” by Andrew George Brown (1950-1982). His daughter has remastered the art and is selling cards and giclée prints in her Etsy store.
There are twelve different submarine drawings and they’re all wonderful. The prints are a bit pricey (over $100) but the cards are only $7 CAD. Check out the cool designs!
