About 8 years ago, I picked up a group of V145-1 cards from a dealer in Canada that had a stamp of a man with a dog. I had never heard of these before but won 16 of these cards with this stamp on the back. I copied his explanation from his listing and here it is:
1923-24 William Paterson V145-1
Leprechaun
Redemption Stamp
--------------------------------------------------------------------------------
The Leprechaun ( aka: Bulldog, Purple Shamrock)
was a redemption stamp placed on the back of
the card after a complete set was redeemed for a prize.
After a card was stamped it was then disposed of.
The thing about this promotional contest was the
company short-printed #25 Bert Corbeau, a card so
rare that its not even listed for a price in the
Charlton Standard Catalogue of hockey cards.
(It just says extremely rare instead of the value)
This would make it next to impossible to easily finish
the set and would make the customer buy more
product to try and finish the set to get the prize ( not known ).
Because there were so few #25's not many sets were redeem.
Which means not many cards were stamped with
the famous Leprechaun.
Since the company had no more use for the
redeemed sets, most were destroyed
I have heard over the years rumors of the existence
of these cards but had never seen them....until now!

I scanned the back of a few of the darker ones (most are quite faded) and enhanced them as best I could with my scanner. Has anyone out there ever heard or seen these before?
Thanks,
