The first thing we see are family photos.
Andy Warhol's mother Julia followed her husband to America in 1921 and occupied her children with painting and drawing at an early age.
She could only write Cyrillic, but for some pictures of her son she tried to use Latin letters, which explains her special charm.
By the way, Andy Warhol was not a Roman Catholic, as one reads again and again, but a Byzantine Catholic, a minority in the minority. The first paintings show a boy grotesquely picking his nose, which was taken as an affront by the art academy, a muscular shirtless man (brave for the time) and two dogs kissing. Provocation is a principle to which Warhol remained lifelong.
