Fun question.  I was eight years old in 1976 and I remember there were all kinds of bicentennial toys.  I got a Tyco bicentennial train set for Christmas 1976.

Doing a nationwide newspaper search for "bicentennial washer" yielded several advertisements for this "bicentennial" model Whirlpool.  Not sure what was bicentennial about it except its model number...LDA 7600.  Now if it came it red and white and blue, that would be been a bicentennial edition!

Apparently Frigidaire made an honest-to-goodness bicentennial small refrigerator (in red, white and blue) in 1976.  Seems like this would be an interesting collector's item.

Thanks DADoES for pointing that out.  Here's a more accurate picture from Sept 18, 1975 that shows the push buttons.  Harvest Gold and Avocado are hardly Bicentennial colors even though this was advertised as a "commemorative edition."

We had a red case on our kitchen TV, can't remember the brand but it wasn't a Bicentennial edition.  I do remember lots of commemorative goods around this time, I think we had a cooler and Thermos bottle with markings like "Spirit of '76".  It was a fun era to be 10 years old. 

...but I remember very well the Magnavox "Spirit of 76" stereo collection. I never ordered any console stereos when I was a department store TV/Stereo buyer, they were already on their way out, but several of them remained in inventory. They were kind of cool in their own way. Once while "branching" (visiting the suburban stores to check your department) I found a half-eaten moldy hamburger tucked into the far corner of the top of a "Dry Sink" stereo. Why I remember that is beyond me, but I recall I was not pleased.

DADoES you are right again, the parts diagram clearly shows four push buttons.  Maybe this is the machine?

In any event, I've learned that newspaper ad print can't be trusted!  It was a different era...probably most of it was done manually with a few stock images that were used for everything.

I'm sure some customers noticed but perhaps expectations for accuracy were a lot lower then.

Didn't Sears have an "All - American dryer" that had a low, curved control panel, that was supposed to match any washer?

A woman we went to church with had a '76 Buick...it looked like my mother's 76 Century but was white with blue across the bottom of the doors and had a blue eagle and something about 76 on it (I was only 5 years old so couldn't read much yet). 

I was 16 in 1976 and only seem to recall a spirit of 76 phone, also offered in plain black (which we had/have):

but a Case 1570 Bicentennial model.

or a 1976 Kenworth Bicentennial edition

Another bicentennial item. A Magnavox "Spirit of 76" secretary stereo. This one's covered up in my garage. I may eventually get to it. For $10 I couldn't say no. It's full of 8 tracks too. 

I'm sure that Buick was white and the blue writing was only at the lower portion of the door.  I'm pretty sure it was a Regal or Century, but like I said, I was only 5.
