Thinking Of You Booklet Puzzle.

Hi all,
I have two examples of the Thinking of You $4.50 booklet, issued in 1992, which were bought at the Post Office at the time.
In both cases the pane was stuck down by the ungummed selvedge and thus the stamps are facing inward and upside down
to normal.
The visible selvedge shows no sign of being interfered with and for obvious reasons I am not game to remove the pane from the cover.

Does anyone have any idea how this could have happened.
Cheers
Ron.

Hi Ron

That a new one on me, I'll look into the variety you have.

Appreciate your interest.

Hi Ron

I know a local stamp dealer who may shed some light on this booklet, will be showing him the image tomorrow.
