I believe there were 3 releases total.
2003, a natural, 22 in a box
2004, a maduro, 22 in a box
2008, don't remember the wrapper color and number of cigars in a box.
Not sure about 2009 and 2010.
Update:2008 has a dark wrapper, a Brazilian Mata Fina. As with the 2003 and 2004 release, each box contains 22 cigars.
