DETAILED (MULTILINGUAL) DESCRIPTION AT THE HOLY SEE WEBSITE: Coat of Arms of His Holiness John Paul II (The Holy See Press Office).

Pope John Paul II's coat of arms.Azure a cross or, the upright placed to dexter and the crossbar enhanced, in sinister base an M of the same (on a blue shield, a golden cross, off-centered to the upper left, with a capital M in the lower right corner).As a bishop, Karol Woytila used this design with the cross and letter in black instead of gold. As this violated the heraldic "tincture's canon" (black on blue, color on color) upon his election as pope, Vatican heraldist Monsignor Bruno Bernard Haim suggested he replace black by gold (Raul Pardo, 2 April 2005,  Joe McMillan, 20 April 2005).
