Umbrellas, tophats and walking sticks, and brooms?
thanks to Steve! I learned this: From "VIII Fighter Command at War: ‘Long Reach’" by Michael O'Leary":
"Reading the aircraft's mission log, three umbrellas denote a trio of top cover sorties completed, the eight top hats and sticks symbolize bomber escort missions (as do the bomb symbols) and the ten brooms [are for] fighter sweeps."
The ice cream cones represent raids on Italian targets and the key indicates the aircraft’s 21st operation.
the goose stepping men symbols represent troop straffing missions, and behind his head are 2 trucks representing troop carriers
50 photograph missions over North Korea, the only photo mission symbols I've seen (thanks Steve!)
