The Window is an item exclusively in the NES and SNES versions of Mario is Missing!. It is one of the windows from Coit Tower, which is stolen by an army of Koopa Troopas that have infiltrated San Francisco. This theft results in the building being shut down. Luigi then takes it back, and shows it to various people within the city so that he can determine where the Window belongs. Everyone proceeds to tell him about the Coit Tower, including unrelated facts such as how it was built in 1934 (it was actually built in 1933, although the murals inside it were painted in 1934). Eventually, Luigi learns enough that he is able to return the Window to the Coit Tower's information booth and receive $1,999 for his accomplishment.
