Who knows where this potograph is from?

Someone made photographs at the recent Penjing Convention in China. This I found in the background hanging on a wall with other old looking photographs. To me it seems to be a Japanese white pine group a few decades ago, possibly in the 1970ies. My own JWP-group is possibly the same bonsai after decades of styling. Does someone know where this old photograph can be found? Some old Japanese magazines, exhibit books, possibly KokufuTen books could be the source.

The orginal of the small image comes frome Julian Antrade's FB site here: penjing foto
