My very first post on cohost was a rechost on 01 Dec 2022 from the account public domain lover (publicdomaintreasures), who, as the name suggests, posted interesting public domain images. As far as I know, they haven't started up the account anywhere else, but you can check out their personal collection of images on their website.

These are woodblock prints by kachō-e artist Ohara Koson. According to Ronin Gallery, the first print is from around 1910, and the second is from around 1912.
