Mid-Century Modern Cherry Wood & Floral Pattern Linen Cabinet attributed to Josef Frank, Austria, 1930s

We have found it in the Czech Republic, in Znojmo close to Austrian border.
According to the original lady owner, her father liked to shop and found and bought it at a flee market in Vienna in the 60s. She didn’t remember that it had any other upholstery since she was still a little girl.
Unfortunately, I couldn’t find it in any Josef Frank catalog, but the quality, the workmanship, the use of materials (solid cherry wood and cherry wood veneer, maple wood and rosewood veneer), the handmade straps, the shape of the drawer, the middle key shield, the base leg, the joints, the curved shape, the design of the plinth, its curves and position and the fact that it is upholstered furniture all refer to Josef Frank.
The tapestry is really not J.F style, but the tapestry is also original from the 20s, 30s, but I cannot say whether this was the first original tapestry…
The cabinet is completely original, except for its back, because I found it without it but we replaced it.
The Linen cabinet received a complete restoration and the wooden surface was polished with French Shellac polish.
Original perfectly working lock and key.
