WHAT : A long time ago in the final frontier, two of the greatest sci-fi franchises were born. Since then, both the "Star Wars" and "Star Trek" series have had their triumphs ("The Empire Strikes Back," "Star Trek II: The Wrath of Khan") and tragedies (Jar Jar Binks, "Enterprise"). Fans can share a laugh about both at this themed art show, where an auction will benefit comic-book creators through the Hero Initiative.
