Around September 1st, 2005, Ashton Potter started using End Cards that
featured a number in the 'NOTICE' triangle. I have three different
examples
with an assortment of numbers as high as 30 on the New Mexico Rio Grande
Blankets end card. In addition to the Rio Grande Blankets, Ashton Potter
has used numbers on the "Masterworks of Modern American Architecture" end
cards and the "To Form a More Perfect Union" end cards. Examples of each
are illustrated on the Plate Number Coil Collectors Club (PNC3) Booklet
web
site at http://booklets.pnc3.org/EndCards/NumberedCards/Numbered
End
Cards.htm.
Any additional information on the use of these new numbers would be
appreciated.
