Hidden in the picturesque passageway that cuts between ul. Meiselsa and ul. Józefa, made famous in scenes from Spielberg's Schindler's List, you'll find this small, kooky art gallery. The free permanent exhibit 'Superheroes' features 160 original acrylic paintings of cats and dogs dressed as popular superheroes, cats and dogs in iconic cityscapes, as well as classic (non-pet) superhero graphics. Doubling as a shop, all original works and prints are for sale at quite reasonable prices, as well as a few other souvenirs.
