Karel Martens - Birthday Calendar

$50.00

The layered and multi-hued patterns in this birthday calendar – made to hang on your wall – are based on a single geometrical composition punched out of colored cardstock in multiple directions. Originally conceived by Karel Martens in 1968, the design has remained unrealized until now.
