Transparent Colored Calendar by Paul Talman, 1980s

The calendar was designed by the Swiss artist Paul Talman in 1969 and realized after his death in 1987 in an edition of 999 pieces. The calendar offered here bears the number 16.
The calendar comprises 31 slides with the numbers one to 31 printed on them; one slide for each day of the month. The slides are held one behind the other in a metal frame that can be mounted on a wall. The foils are yellowed (no smoke!) and show light shadows from the other numbers. The metal frame is also slightly yellowish and has two small scratches. This piece has an attribution mark,
