Tee shirts galore, we guess

Hey Diane. . .
Don't bother bringing your 65ers tee-shirt to the Antiques Road Show just yet. Not as valuable as first thought, apparently. I guess there are a lot still around. Lorlee writes to say she has hers, and Sara says she has TWO of them.
Hmm. Maybe that's where mine went. Sara?

Stan

==========================

Yes, seeing that people can't tell us apart because you and I are so close in height and weight I stole your tee shirt thinking you wouldn't notice. Guess I was wrong.

Sara

==============================
Dear Stan,

I wasn't just going to bring the '65 T-shirt; I was going to wear it. How about that?

Sincerely,
Diane McCarthy Hendricks
