Czechoslovakia Shortwave Radio Card, 1969

I have no idea what the young woman is holding in this picture. A very oddly-shaped picnic basket or carry-all? Some component of the motorcycle (which might technically be a moped anyway)? Anyone know? (Well, I got my answer. Scroll over to read.)

From the Central Radio Club in Prague to Radio W7BDU in Portland, Oregon. (Shown slightly larger than original size.)
