This is the first special edition card for the cardgame The Settlers of Catan. These special edition cards where only produced in a limited number of 500 copies so they are extremely rare, especially this first edition.
It was also available as print&play version for people who finished the Professor Easy online tutorial. Two versions of this exist; one for the base game, and one for use with the expansions.
Later, the card was included in the Barbarians & Traders expansion, but with a different image and improved effect (not only reducing cannons, but also dragons to 2 strength points).
The text on the card says:
Johanna, the warrior
Opponent's cannons only account for 2 strength points. Immunity against Imelda and Bribery. Requirement: Church, no Citadel.
