Does Anyone Sell Chen Hongshou Art on a T-Shirt?

Yes. Vestige Press currently sells 2 different Chen Hongshou works printed on heavyweight garment-dyed t-shirts, each made from an archival public-domain scan of the original and numbered as an archive plate. They are listed on Etsy at https://www.etsy.com/shop/VestigePress. The Chen Hongshou designs sit in the grunge style category of the archive.
