What's for sale?

This is a nice example of 1970s desktop style. A perpetual calendar in dark green plastic with manually-operated roll-over panels.

Operation is simple; the day, date and month are incremented by four matching dials on the top of the calendar at the rear.

This is a German language calendar, so days are represented by ZO, MO, DI, MI, DO, FR, SA and the months by JAN, FEB, MÄR, APR, MAI, JUN, JUL, AUG, SEP, OKT, NOV, DEZ.

The Dati was also available in dark brown and bright orange. To us it is the bright orange and green which seem to symbolize the 1970s; we associate both colours with Porsche 911s of that time.

Who made it and when?

It was made in the 1970s by (West) German company Arlac, a specialist in deskware and stationery.
