This card was part of a 2008 team set put out by the Newark Bears, who Rickey played for during parts of the 2003 and 2004 seasons. At the end of the set were a couple of black & white cards that featured famous Newark Bears alumni. I'm not sure how it managed to allude me for the past two years, but I had never even seen one until someone offered to sell me the card in an e-mail about a month or so ago.

The Newark Bears have been on pretty shaky financial grounds the past few years, and were bought out of bankruptcy by new management in 2009. I don't know the print run on the 2008 sets, but I don't believe many of them were produced, and have heard that any remaining sets might have been destroyed when the new management took over.
Here's a list of all of Rickey's other Minor League cards (at least, until another one pops up that I didn't know about):
1977 Modesto A's
1979 Ogden A's
1989 Modesto A's
2003 Atlantic League All-Stars
2003 Newark Bears
2004 Newark Bears
2008 Newark Bears
