I had the rare opportunity to see this on the big screen about three years ago as part of a night of UPA shorts with creators and animators in person. I've seen this on DVD since, but nothing can compare to the effect of the simple lines and fifties modern art influence than when I saw it on the tremendous screen at the Egyptian Theater.
The Hubley's were an oasis of artistic creativity in the 50's. As a little boy who loved making loud noises I was a big fan of Mr. McBoing-Boing. I had the book and love(d) the movie! Errooow! Bang! Bang! Rrrrraaaaatttchhhhh! Erperperp! Ahoooggahh!
