I picked up this guitar in August of 2008 and it has a market value of $1,137.00. It's a parlor sized guitar built somewhere around 1830-1840 by Jens Nielsen Gade (1788-1854) in Denmark. There are 2 labels inside that indicate restoration work in 1854 and 1871. There is a pencil inscription inside that I believe reads JE Sorensen April 1870. There has been some more modern restoration work done with modern glues. As far as I can tell, this guitar is all original and complete except one bridge pin has been replaced. This is a beautifully built guitar that in the hands of a good restorer will be worth thousands. Dimensions of the guitar: Length is 36 inches, lower bout is upper bout is 11 1/4 inches, upper bout is 8 3/4 inches, and thickness is 3 1/4 inches.

This is an interesting book on Danish guitars. http://www.elderly.com/books/items/570-1.htm
I was told this guitar came out of an estate in New York and in fact there are storage tags for Rochester NY and one for an Amelia L Harris in Salisbury PA included in the guitar.
