i can't help with the value but judging by the logo on the label it's from the early days of Tanglewood, strictly speaking it is a classical guitar rather than a parlour (which would have steel strings rather than the nylon ones fitted here)
a good start would be to look at the edge of the soundhole and see if you determine if the top is made from solid wood or ply, Solid would indicate that it's a better quality guitar as ply is generally only used on the cheaper guitars.
some pictures of the back and sides would also help to determine it's true value. It looks like a fairly nice instrument.
