Three more issues have come out since Jan 3:
Jan 12, 2009 50th Anniversary of the National Marine Defense Q1.00
Feb 6, 2009 National Celebrations (UPAEP 2008) Q0.50 / 2.00 / 3.00 / 5.00 and souvenir sheet Q 8.00
Apr 14, 2009 Typical Costumes of Guatemala Q0.50/1.00/2.00/3.00/4.00/6.00/8.00/Souvenir Sheet Q10.00
The above comes from ISGC's website but there is a mistake or a missing stamp from the Typical Costumes set. I have a Q5.00 I picked up at the PO last week but there is no Q5.00 listed on the site.
