Vancouver skeptical artist Gary Lyons created an amazing poster for the upcoming Skeptics’ Guide to the Universe & George Hrab – Live in Vancouver event on November 20th, 2010.

We loved it so much we asked for larger-sized artwork to upload as desktop wallpaper and he graciously complied.  It’s been extended and sized it to fit on both 4×3 and 16:10 (widescreen) displays.
