Portable Desk Easel

I am a pen and ink artist, and sometimes a standalone easel is hard to carry around and set up. I recently attended a brunch meeting of former car racers who meet regularly. I wanted to show some of the portraits of them that I brought along. A large easel wouldn't fit so I designed this smaller easel to display the drawings. I holds the artboard on which I draw very securely. Below is one of my portraits in the easel. The subject is Paul Newman.
