GUEST: This is a helmet that Charles Lindbergh wore, and it was given to my husband's grandfather.

They first met in about 1924, when Charles enrolled in the Army Air Corps, and my husband's grandfather, General Cannon, was one of his flight instructors there.

Then, four years later, they met again at an air show, and General Cannon lent Lindbergh his plane to use in part of the air show.

APPRAISER: Wow.

GUEST: So, at the end of the air show, Lindbergh presented this helmet to him, signed it, then dated it.

APPRAISER: Wow, that's an incredible story, and what an amazing gift.

GUEST: Yeah.

APPRAISER: Let’s have a close look at it.

What we have is a, is a, is a pretty basic flight helmet for the 1920s.

Uh, simple leather with a, a buckle strap.

And you have these two snap straps in the back that would secure your goggles, so they wouldn't blow away.

GUEST: Mm-hmm.

APPRAISER: And honestly, at this time, its main function really was just to keep your head warm.

And as you mentioned, it also has Lindbergh's signature right here on the side flap.

GUEST: Mm-hmm.

APPRAISER: Charles Lindbergh," and it's dated September 16, 1928.

GUEST: Yes.

APPRAISER: Incredible.

Lindbergh was a complicated American historical figure.

Uh, right before World War II, he had an isolationist stance, and he did express some anti-Semitic views.

Lindbergh dropped out of college after two years to join a flight school in Nebraska.

After that, he was barnstorming across the country, wing walking, and doing all kinds of daredevil stunts.

which is when he would have met your husband's, uh, grandfather.

APPRAISER: And made his historic flight solo, nonstop, across the Atlantic, May 20, 1927.

He climbed aboard his plane with a couple canteens of water... (both chuckle) GUEST: Yeah.

APPRAISER: and I think a, a couple of sandwiches... GUEST: Yeah.

APPRAISER: and some 33 hours later, landed in Paris.

GUEST: Mm-hmm.

APPRAISER: and it's an iconic kind of symbol of early aviation.

GUEST: Yeah.

APPRAISER: So, now we also add to that that he signed it and dated it-- so 1928, September, just a little over a year after the historic transatlantic flight.

APPRAISER: So, it ticks a lot of boxes for folks.

I would conservatively say, at auction, we're talking about something around $8,000 to $10,000.

If I were to insure it, I would think we'd be looking at $20,000.

GUEST: Okay.

Okay.
