Hi, I am the daughter in question here. I was actually only 11 when I had this interaction with Arthur. I only got told “no” on one occasion. It was Michael Golden at the Dallas Comic Convention. I will never forget that interaction either. Although a few years later I did get Michael Golden to do a Bugs Bunny sketch for my younger brother.  I was always very respectful to artists, and I was actually quite shy as a kid. My dad having me go get sketches on my own was what got me over that so
