I did. I googled for it and no one has his drawing. He did mention to me a US Naval site or something like that but I have forgotten the name of the site.

You have sphenomegacorona! I am very sorry to hear that. Drink plenty of fluids and get lots of rest, it will be gone in a week or so.

What is that?

Actually I never watch Star Wars and not interested in it anyway, but I choose a Yoda card as my avatar in honor of our great friend bobbym who has passed away. May his adventurous soul rest in peace at heaven.
