Re identifying the uniform: I showed the photo to an expert in military uniforms of the era and he thought they were POW uniforms. They don’t match any military uniform of which he was aware. Before I even learned that my grandfather had been a POW, he suggested that it was a POW uniform. It is similar to an Austrian uniform, I think, but I have to double check that.

Does anyone know whether there was a POW camp in or near Vienna during WWI?

Thanks again,
