1) Toni shared a link to an online jigsaw puzzle of a painting from the 19th century for Mirka to solve, giving clues that the artist's initials were SJL and it was painted during the Napoleonic era. 2) Toni chose this painting because she loves the Napoleonic era due to Napoleon's military success and she enjoys the realistic colors and atmosphere of the painting. 3) Toni provided questions for Mirka to answer about the painting's artist, title, date, size, location, and whether she likes it after solving the puzzle.
