Window Thank You Cards

Window card with swinging "Thank You" sign.

The window is actually a plastic film and behind it is a small "Thank You" sign that swings on a cord.

I found these window cards in two sets at the Goodwill Store in Cerritos, CA.  The back of the card says it's from Rick Shaefer Design, 2005, by Leap Year Publishing.

I was attracted to them because each card has an actual window with a clear plastic film, and behind the window is a "Thank You" sign that actually swings on a cord.  I actually sent some of these out as thank you notes for Christmas gifts.  The cards are not too thick so I was able to mail them with a standard 49 cent forever stamp.
