My father-in-law bought this pair of woodcuts from 1854 at auction. We have a lot of information about them, and we've translated the cartouches, as well as the date mark and aratame seal. The only mystery is the mark that I've indicated in images 1 and 2. We suspect a publisher or cutter's mark? If anyone has any insight we would greatly appreciate it!
