A sign pole with its own knitted vest

Cart and I were in Trastevere over the weekend. There were more people roaming around than usual, but that was expected due to the popes’s canonization.

We were walking along Via della Lungara when I spotted this :

A sign pole with its own knitted vest isn’t something that’s commonly seen. I wonder what was the motivation of the one who was responsible for this.

Is this part of a political statement? Could it be involved with a Yarn Bombing?

Nevertheless it looks so cheerful and gave the pole a little festive and unique look. I do appreciate the artistic value of installations like this and this compared to many of the ugly graffiti that we see around.
