More of an extended postcard than a greeting card, nevertheless it is folded in thirds (made that way) and opens to reveal the 12 lighthouses you see in the scan.  When folded, the reverse acts as a postcard and was mailed in 2012 with stamp and most of the postmark.  Please do note that this is not a conventional postcard–just think of it as a very long one, that folds in thirds.  Grade: 2
