Rome wasn't built in a day ..

Having visited the Colosseum earlier this year,  I've now created my own version of this great building, complete with a huge crowd of visitors from all over the world. The Colosseum itslef is constructed using mainly Italian stamps, and you can spot Julius Caesar and Augustus the gret behind the arches.  As the saying goes, "Rome wasn't built in a day" and this stamp collage took me several weeks to complete but that's not long compared to the real Colosseum which took more than 8 years to build.

I would welcome comments on the stamps included in this collage from anyone with a knowledge of Italy's history! I made this some time ago, before researching the meaning of the red 20c stamp "I Bimbi d'Italia si chiaman Balilla" and discovered that stamps issued around this time often carried propaganda messages.
As I'm shortly going to be visiting Rome, I was also trying to find stamps portraying famous Romans, and found Julius Caesar and the Emperor Augustus too. Stamps showing King Umberto I, Victor Emmanuel III, Italia and Provincial occupations such as weaving, harvesting and fishing are also included.
