A Food Cart Vendor at Grand Central Terminal

I made a quick sketch of a food cart vendor near the Vanderbilt Avenue entrance to the Grand Central Terminal over a week ago.  Once I got home, I added some watercolor wash to it.  This evening, I saw the same food cart vendor and couldn't resist showing the sketch to him.  Basically, I wanted to add a name to the food cart vendor in my sketch.  He was amazed and asked if he could have it.  "I don't tear out a page of my sketchbook" was my reply to Moustafa but I did let him take a picture of it instead.
