Closeup iPhone 6 image of the signature of Mike Reiss, from my copy of the book City of Hamburgers that he signed in 2012 after an event in Aspen, Colorado  
 during a book signing. I cropped the image to get just the signature. There are two versions of the image I have uploaded, one is a jpg file and the other is a png file.
