Colour Collin, albeit a guess.
The image was taken from "Cinderella Corner" in the
Australian Stamp News Circa 1970
I began my stamp collecting with Cinderellas,
and that was one of my first scans, I wasn't into dating them at that time, I didn't keep the associated commentary either.
Actually I am in two minds whether they may be poster stamps.
I have some Ajman Dunes that illustrate Olympic history
that look very similar to these, I'll have to dig them out.
..not Ajman, Umm Al Qiwain
miniture sheet lopped to accomodate 90Kb limit
the posters of the early olympics.
I think the 1900 expo black and white are poster stamps.
