The Mets have released their Bobblehead giveaways for the 2013 season. Last season the Mets had Rusty Staub, Tom Seaver, Keith Hernandez, Edgardo Alfonzo, and Mike Piazza.
I was fortunate enough to get all but Hernandez (still looking for a reasonable price on e-Bay).
This year there will be some more Bobblehead giveaways at GHMP:
According to ESPN's Adam Rubin, the Mets will offer:
April 21, 2013 - Ron Darling
June 30, 2013 - David Wright
July 21, 2013 - Dwight Gooden
August 25, 2013 - Tom Seaver
I would love to see the Mets re-visit some of their older "glory" with such player Bobbleheads as:
2013 raises optimism,,,unfortunately it is for the Bobblehead giveaways, and not the team on the field.
