If you happen to find a print by Harunobu or Utamaro in a shop or at an auction sale, and it is in good condition, it is probably a 20th century reprint. In some cases these reprints are clearly marked with the publisher's seal. I have now collected some of these seals on a web page (see below).
If you know other seals in this category, or if you have additional information on the seals already posted, please send an e-mail message or post a reply here.
