Came across this website which has a desk calendar featuring dates in women's aviation. That's a calendar I've been searching for for a long time, indeed, if I had had the financial wherewithal myself I would have made one meself and put it on the market.
Anyway, they beat me to it, and I ordered it today. I'll report on it when I get it, but if you know of anyone interested in aviation, (female or otherwise!) send 'em this as a Christmas gift!
