Delving into the past

Not sure when this photo was taken. My grandfather was a sculptor - brought up in Russia until moving to Hungary I think in his late 20s (early last century). Had more talent than me. I would have liked to ask him about his development as an artist or even watch him as he worked. Alas... In his later years, after moving to Australia in the 50s he took to painting and knocked out some landscapes with oil as well as pencil drawings. I was a bit young to ask sensible questions while he was still alive. At least some of his work remains.
