This is a vintage greeting card from Artistic Card. It reads "To a Shut-In, May health be the treasure you soon will possess, to keep the years filled with real happiness!" The front has a cut-out section (shows blue in the pic) and features a flower, possil a cattleya orchid? There are more floral designs inside. The maroon/burgundy part of the flower is made of felt.
It is unused with no writing but there is a 1" tan spot near the bottom edge from the front (not too visible) thru the 2 interior pages. It is age tanned, too. It comes with an envelope which is not the original envelope.
