This memory game includes 24 pairs of cards featuring remarkable historic illustrations. The flowers that adorn each card were hand-painted by an unknown artist in the early 1600s onto the blank sections of a christening book published in 1596 Bavaria. How to play: Shuffle the cards and arrange them face down in rows. Take turns flipping over any two cards. If the cards match, keep the pair and take another turn. If there's no match, turn the cards back over and play moves to the next player. Continue until all 24 pairs have been found. The player with the most matched pairs wins. For solo play, try to beat your own record by finding all pairs in the shortest time or set yourself a fixed time limit to find as many pairs as you can.
