According to your feedback, the most difficult puzzles remain the domestic visual riddles from Tsarist Russia. Fortunately, with the advent of the Internet, the “guardians” of library archives now have the chance to disseminate these works to the public, making them available to all.

To show how difficult these problems from Tsarist Russia can be, we invite you to attempt today’s challenge. Look at the puzzle: a youthful couple—or at least the lady appears to be young—stands beside their spacious mansion. They were visited today by a photographer with whom they had been waiting for almost a week to take a family shot.

The couple has a son named Aleshka, but he appears to have gone missing, so the family portrait may not take place after all. Can you locate the couple’s son? Aleshka, where are you in the picture?
