Swap Meet Find...italy, Belgium, And Some South America

I was at the swap meet yesterday and was left unattended for about 5 mins and so picked up some stamps for my daughter (she's the collector, I'm just a hoarder).

This is our first real foray into world stamps, until now it's just been "hinge the odd stamp you find on a stock page". We were fortunate to find some European album pages online and will probably print the pages as needed.

I'm sure most of the stamps are 'bunk' but they are honestly secondary to the time spent with her- all the same, is there anything we should keep an eye out for? I probably have to ask that *after* they're mounted... They all are 1950s and earlier, there are some newer ones from Italy too.

Thanks and I'll keep yall posted about what we find.
