Peter Tatar dulcimer
No one I know could afford this but it's certainly interesting and worth documenting. It was evidently made by Peter Tatar (Sr) since Peter Tatar, fils, would have been 9 years at the time. The other question is that it is dated 1958 but the sources I found have him immigrating to the US in 1959. Was this made in Italy?
In any case it is clear that he was working from a Jethro Amburgey pattern. Does anyone have additional information and are there others out there?
