Spectacular ERROR stamp Block - $A165: The 2020 Australia Year Books I bought all had a very spectacular printing error in there - the entire word AUSTRALIA was *MISSING* on one $1.10 stamp as well as issue year - see photo above. A huge error in this modern era. NORMALLY the PO would simply swap them over for the corrected version, before placing them on sale - but this year, for the first time ever, all the 2020 annual books did not have stamps loose as usual in a cello bag or Hagner, that you then placed in yourself.
They are now for each set, all printed on a page of gummed paper, with design all around them, as you can see on pic above, and perforated within that A4/Quarto sized sheet. Each page is like a huge A4 size mini sheet essentially! So to swap these over by PO, would mean all the completed Year Books had to be destroyed, new pages for that error set printed, and then the entire book totally re-printed again, and that page newly bound in. WEEKS of work. As the error was not noticed until almost the on sale date, https://stampboards.com/viewtopic.php?f=27&t=93348
it was WAY too late for all that, as books are bought heavily each year as annual gifts, and in recent years, sell out very fast. They are not re-printed. The CORRECT stamp wording was on course on stamps in all the PO packs, on FDC, and in usual mint form etc. Tons more detail here - www.tinyurl.com/Glen1-21
