Flickr friend John4kc is a retro recon junkie, and has many wonderful photos on his photostream (click the photo to get there). This Nutone door bell is a classic – but be still my beating heart, how I adore that vintage wallpaper. The graphics, so sweet!… and chartreuse+pink+green+red on cream — a most wonderful color combination. Thanks, j4kc!

Vintage wallpaper is always so happy and gay (the 1950′s definition). One wall of it really brightens up a room!
I completely forgot that as a child we had that doorbell. Ours had 3 chimes. (Hmm, wonder if I have a photo around here someplace.)
I love the way photos like this one of wallpaper can bring to light a pleasant memory – that I had completely forgotten!

Not a NuTone, actually a far less common model by Liberty. Dana<c remembers correctly: there was a 'deluxe' model with a third tube (decorative) which hung so that its length was midway between the other two. With few exceptions, chimes with three tubes and with two tubes do the same "ding dong" with the center tube being decorative; it was the ones with four that used a little motor to ring out a tune, usually 4 or 8-note Westminster.
Thanks for the clarification, Jonas!
