First Day Covers, 150 Years of Australia Photography, 13 May 1991, Perfect
Condition

These have been stored in darkness in Mylar archival sleeves for their entire
30 years, so they're in perfect condition.

They celebrate the Australian photographers:
Harold Cazneaux, 'The Wheel of Youth', 1929
Olive Cotton, 'Teacup Ballet', 1935
Max Dupain, 'Bondi', 1939, and
Wolfgang Sievers, 'Gears for the Mining Industry, Vickers Ruwolt', 1967

I curated a collection of historic photographs at the time and was privileged
to meet Olive Cotton on the day of their release.

Make me an offer!

I'll send them in a suitably stiffened A4 padded envelope.
