The person in rags in this image looks young for sure, and he didn't have to waste much money to find a disguise to have fun during Carnival.
With a poor guy's cane, compared to what nobles were using at the time. Maybe it was also a way of begging for some pocket money during carnival? Just a thought.
In another reproduction of this same image, there is some text added, which sort of explains why and how he became poor, that goes like this:
"Son belle dòne amante poveretto
C'vi chiedo d'Amor qualche marchetto."
"I am poor because of beautiful women
And so I ask for my Love, some pocket change."
