All I can say is "WOW!!!"
I hate abbreviated vestments, especially the "fiddleback" chasubles. But I'll make an exception for this one. It's amazingly beautiful! Apprently, it's from John Paul II's town:
Wawel Cathedral’s 500-year-old chasuble ranks with the world’s top masterpieces of Gothic needlework. Its relief-like three-dimensional scenes from the life of St. Stanislav, Krakow’s 11th-century bishop-martyr and Poland’s patron saint, embroidered with unbelievable precision and realism, match the best sculpture of the late 15th c. Naturalistic features of tiny heads and detailed faithfulness of depiction (complete with open wound on the saint’s skull where sword struck) are truly stunning. And masterly, dramatic composition arrests attention.
