This is another piece that took a few years to finish, mainly because I didn't know how to do the math (it turned out to be algebra). It started as an idea in 2012 when I saw "Avengers," and I eventually started real progress in 2013. I had hoped to have it finished and to get into San Diego Comic Con in 2015, where I would acquire all of the actors autographs...I didn't finish it until Mar 2016. But I have begun to acquire autographs-- Silicon Valley Comic Con 2016, I briefly met Jeremy Renner!
