Happy, happy indeed!
WOW, fascinating to see an original. Almost didn't even notice the whiteout! Do you know at all why the boxes and text weren't inked? Was it so that they could be rearranged in papers, and the text changed for different languages and done by the newspaper editors?
The text was inked. Watterson used a technical pen for inking, and they don't use India ink. So what you're seeing is ink that has faded, either due to the acid in the paper or exposure to the air.It is very cool to see it. Original Calvin & Hobbes strips are rare... on the Internet they're rare. In real life, they're probably non-existent outside of Watterson's home!
