Interested in knowing which state flag dates back to when in the same
form as it was originally adopted ? Just the oldest, when and some
provenance that it is the oldest (eg website). Thanks

Hi wolvies:

Thanks for the interesting question. 

It appears that Texas has the oldest (i.e., unaltered in continuous
use) state flag in the U.S.

Quote: "The official flag of Texas was adopted in 1839, six years
before it became a State.  Only the flag of Hawaii is older as an
official state flag, and many Texans would be quick to point out that
Hawaii's official flag was modified in 1845 so the banner that
represents TEXAS is the OLDEST ORIGINAL official STATE FLAG."

Quote: "A bill describing the 'Lone Star Flag', a flag that would
become the second official flag of the Republic of Texas, was
introduced on December 28, 1838 by Senator William H. Wharton. The
bill was, of course, referred to committee and this committee proposed
a substitute bill including the same flag design proposed by Senator
Wharton. This bill was passed by the Texas Congress on January 21,
1839 and approved by Texas President Mirabeau B. Lamar on January 25,
1839. This was almost six years before Texas became a member of the
United States of America."

That's fascinating, I was assuming it would be one of the original
colonies, probably a New England one. I wonder why all of those were
tinkered with. Thanks very much - great answer !
