This is a set of fifteen Frederic Malle postcards. Each postcard features a drawing done by Konstantin Kakanias that goes with a fragrance in the Frederic Malle line. Mr. Kakanias, an LA-based artist, also illustrated Mr. Malle's 2012 book, "Frederic Malle: On Perfume Making". As a matter of fact, the illustration on the front of that book is also one of the postcards. The postcards are held in a paper outer folder with an elastic band to keep the postcards from falling out. That folder measures 5" x 7". Each postcard measures 4 1/2" x 6 1/2".
