This was given away at Wrigley Field to the first 10,000 fans on August 31, 2009. During the season, the Cubs gave away four different bobbleheads: Ernie Banks (May 12), Ryne Sandberg (August 11), Billy Williams (August 31), and Fergie Jenkins (September 29).
The box says "Rookie of the Year 1961" but the picture on the box is from the mid-70's.
The statue is a real mishmash of eras. The uniform is what the Cubs wore between 1958 and 1968, but the face of Billy has a mustache, something he didn't have until late in his career. If you ask me, the face doesn't really look like Billy at all.
I will give the manufacturer a little credit for the back, as they got the Cubs unique number font correct. They just needed to make the numbers a little bigger...
I don't think I'll become a bobblehead collector, but I couldn't pass up getting one of my favorite player.
