In the episode "Vote for Brady", at the end the family is celebrating Marcia and Greg's race for student body president. There is a cake at the dining table and the family is talking at the end of the episode. Mike is seated at his usual end position. When he is talking there is a china closet behind him as there is a wall behind him. Do we ever see this China closet again? I checked the episode where Peter breaks the vase. There is another wall and painting behind Mike Brady. There is not a wall there but does the China closet ever make an appearance again or is this a one time scene.
Its sort of like the glass sliding doors in the parent's bedroom are only seen in one episode: Mike's Horoscope.

Not that weird really because that wall between entryway and first sliding door was rarely shown.

I dont think there ever was a wall there. I think it was used only as a backdrop when Mike sat in the chair. When they built the Brady House, they never put a wall there.

I think we saw a wider shot of that when Peter has his party at the end of The Hero.
