What a surprise to get this postcard back from Helena! We haven't been to Helena for some time--a couple of years at least! The corner that would have shown the year is ragged, and on the other side I think there was contact information for the finder on that same corner. This card was placed before we started keeping track on this blog, too, so there's no URL for the finder to look up. I do have a Helena contact, though, so we may thank this finder yet!
Especially since this finder was kind enough to add postage. There's more than enough on it now! The finder wrote:
Heyyy,
I found your postcard in a library book. I figured you might be missing it so I'm mailing it home to you.
