Hey, Did You Know It's the 40th Anniversary of Woodstock?

In case that new movie with Demetri Martin and the rash of Woodstock-themed books (including children's books) didn't clue you in that something was going on, we're here to tell you that Woodstock, the famed music festival, happened 40 years ago this month. From August 15 to August 18, 1969, music fans gathered in a field in Woodstock, New York, to smoke weed, roll around in mud, and listen to some pretty decent music. Artists ranged from Joan Baez to the Grateful Dead, and the festival has taken on epic proportions in the minds of music fans ever since.

The festival's original poster, too, is iconic: the peaceful dove, the two-color guitar. Now, in honor of the festival's anniversary, original poster designer Arnold Skolnick has created a new poster (pictured). Still featuring that dove, the new poster also lists events from the era that shaped Woodstock and so many people's lives.

Tonight at the International Poster Gallery (205 Newbury St), Skolnick will be on hand to sign posters and give a talk about his designs. The gallery has acquired several other Woodstock posters for your viewing (and possible purchasing) pleasure as well. The event runs from 5 to 7:30pm.
