The Ring-A-Date Perpetual Calendar was designed by Giorgio Della Beffa in Italy in the 1970s and produced by Euroway in Turin. It's a classic design and an important part of the Italian plastic designs that were created in the 60s and 70s and took over the world in these decades within interior design.
Now, about 50 years later, the grandchildren of Giorgio have given their grandpa's famous design a new life. They have re-issued the Ring-A-Date calendars. Created from ABS plastic that has been pushed into a mold to get it's shape in three great colors: White, Yellow and Green.
