Re: TitanicIf you compare a single souvenir sheet sold at any post office to the 'same' souvenir sheet seen on the uncut press sheet sold by
Canada Post you will see a subtle printing difference along the top of the pane ... clearly there was a 'philatelic' uncut press sheet (qty. 5,000) vs. a production-run press sheet used to print the 300,000 souvenir sheets sold singly.
I suspect the production-run press sheet had 20 souvenir sheets per sheet (compared to only 12 on the 'philatelic' version).
The July-August 2012
Corgi Times (page 7) illustrated and discussed a corner fold error found on a Titanic souvenir sheet. The additional printing markings seen on the corner fold are
not present on the 'philatelic' uncut press sheet. More evidence that
Canada Post is specifically producing collector-oriented uncut press sheets that are different from the regular production-run press sheets.
Re: Other 'philatelic' uncut press sheetsI would suggest that most (perhaps every?) Lunar New Year uncut press sheets had a different, 'philatelic' version.
Certainly the following souvenir sheets (issued with a tab containing a UPC barcode) had a different press sheet compared to the 'philatelic' version sold to collectors (where there are no UPC barcodes present):
* 2003 Year of the Ram
* 2004 Year of the Monkey
* 2005 Year of the Rooster
