I have not, but the stamp isn't the only good reward you can get from it. It's probably not as consistently valuable as the bank or stock boons, but if you can win big then you REALLY win big. But also with the amount I've got in the bank it's not like the bank boon is that worth it in my case, and I'm not a fan of the stock boon either, so at some point it really comes down to preference.
As I already said, the rewards from the bank and stock boons for 7 days are too minuscule to compare because both require a longer time frame to be profitable.
I have seen screenshots of people who have gotten the stamp with the cartography boon active - so I guess it's still possible.
With so many people activating this boon, I can believe that the chances of getting the stamp drops significantly, but as someone mentioned, the chance is there when you can make it to the treasure room.

When I can play, I gladly choose the Cartography Boon in the hope of winning the stamp or at least the brush but unfortunately I don't even see the crumbs of luck.
