What does the Buick trishield represent?

Hmmm..... that's a good one. Of course, B-59s didn't fly under the TriShield... Gonna have to guess on this one.

The red, white & blue clearly represents the U.S. Flag.

The earlier Tri-Shields encompassed detailing carried over from the earlier, single shield crest ('40s & '50s but dropped for '59); the antelope head, the cross, the checkered band (the later represented as seen in the above emblem).

What I cannot positively ID is the representation of 3 - was it a take off of '59s 3 diamonds, representing the 3 model lines? Doesn't make big sense to me, as Buick clearly would've been working on the Special by '58-59...

Even when you are making educated guesses you get it right.....

Introduced in '59 for the 1960 year.

It originally represented 3 models.

The LeSabre, Electra and Invicta.

Buick emblems evidently were derived originally from Dunbar Buick's family crest.

You know I hate that the Tri-Shield is commonly ID'd as beginning in '59. Technically that's correct, of course, but the car world revolves on model years, not calender.

Agreed.... after all, there's no 64.5 calendar year as every Mustang guy refers to...!?

By this goofy definition the 1969 Camaro was made for three years!

Production started in 1968 and did not end spring of 1970.
