These postal memories can often still be found in flea markets, yard sales, antique stores and grandma's attic, but it's doubtful you'll be finding any for a penny any more. I bought my first one for a quarter--I saw the same one recently at an auction selling for several dollars.
Here is an assortment of cards depicting various scenes and buildings around Henry County. The collection is a bit heavy on Kewanee as that is where the county coordinator's personal interest lies, but contributions have come in for other areas as well.
If you have old postcards from the area, please feel free to scan them in (try to keep the scans as close to the original size of the card as possible) and submit them via EMAIL.
