3 sets of apparent glyphs from the San Andres archaeological site, including the 3 Ajaw symbols from the San Andres cylinder seal (the entire print can be seen at Image:San Andres Cylinder Seal print 1.svg).  The two lower glyphs were found on shards of a greenstone plaque.  The gray lines represent the edge of the shattered plaque.
