Cannot find on lionelstore.com but found them in the 2013 cataolg:
MLB Berkshire Set A. New York Yankees Steam Berkshire Set 7-12000 page 66
New York Yankees/Mets Subway Series Set 7-12016 page 64
Anyone know the status? I just sent messages to Lionel but obviously this is an emergency. I would, of course, paint graffiti on the Mets stuff.
