well there is something legendary related to this specific comic strip.What?
This is the Publication of peanuts which was published on March 30, 1993 in which Charlie Brown finally scored a home run after 43 years of peanuts.
AND Please give a big round of applause to Pankaj for giving the second angle to the question, i.e.
the second legendary thing about this strip is Exactly 15 years later Ryan Zimmerman hit the homer in the ninth innings in the Opening baseball night at the National Parks with the Washington Nationals beating the Atlanta Braves 3-2 and this being the first homer on this park.
Also Bush threw out the first pitch that night.
