My 2006 Snowflake FDC with the 2006 ALA Regular seal and predecessor seal tested in 2004.  This one sells for $3.95 and uses a unique GREATFDCS (Jack Ginsburg) cachet.  I also have 5 FDC covers that also has the 2005 test seal (the rare T1)for $9.95 while they last (3 seals, same design, 3 different year dates) . Look forward to my Christmas Day classic covers where all five (5) test seals for 2006 will be on two covers (plus the Spanish inscription seal).
