This is a book of 24 beautiful Art Nouveau posters made into postcards. I bought this when I used to collect postcards. They are unused, but there is some age-related deterioration on the back. The designs on the front are beautiful, so how about using them for interior decoration? Due to the yellowing on the back, it may be difficult to use them as postcards, but all the designs are very lovely. - Title: Twenty-Four Art Nouveau Postcards in Full Color - Editors: Hayward and Bernice Coker - Design Style: Art Nouveau - Number of Postcards: 24 - Condition: Unused (Ready to Mail) Thank you for looking.
