Can anyone tell me when the window in the living room came about. I know the first couple of years there wasn't one and then in the episode Lucy and Superman suddenly I realized that there are some episodes with the window. Was there an episode that dealt with the Ricardos getting a window?

Yeah, you should check out the episode titled "The Ricardos Change Apartments." Lucy wants a bigger apt. since now there are three of them and they work a deal with a lady downstairs to trade apartments. Thus, the window!

Ah, I haven't seen that episode but I remember seeing that episode title in the episode guide of an I Love Lucy book I have.

Thanks.
