Madonna's concert tickets for sale!

I would think that in the age of the Internet, people who bought tickets to a concert they finally cannot attend would sell them on ebay or post a note in a music forum...I was wrong! The old techniques are still around, like sticking a little paper ad on trees in busy streets saying "I have two tickets to the Madonna concert to sell" with a telephone number. I don't know if they managed to sell their tickets, but I thought it would make a funny photo ;) BTW, the tree is a platane (plane tree) like many of the trees you find in the streets of Paris.
