Surely the book at today not yet published ... but... mybe there is around a not-ufficial copy ...(really i don't know!) but ,.. if this copy exists,... it would be interesting to have some news about
the search result on an unpublished book by late Mr Bambang Hasri, but it is not about Solo/Jogja sarung...its about keris in general.
I'll keep searching for more information.
