This lot of 8- seashell booklets are from 1984, and are in The Scotts catalog as # 2121a. MNH. They are a series of 7 booklets that feature a "floating design." The artist, Frank Waslick painted a strip of 25 different shells that were repeated across multiple booklet covers. The P.O. packaged 7 booklets together so people could see the complete painting. They are also the first intaglio web- fed stamps printed with blending technique. The seven booklets make up the complete painting and the 1- extra booklet is for you to be able to see the actual stamps. Due to their age, some of the booklets have become un-sealed. They would look amazing framed. Please refer to the photos for reference, and thank you for looking. Make sure you view my other treasures .
