Hello Ramdan,
thank you for sharing those pictures of Malang. It was my birth-place (1942 - Japanese Occupation period), and I walked there in october 2007. I stayed at Enny's GuestHouse. I can send you some pictures, if I know how to do it.
I'm also very interested in (old) pictures of the Tjelaket/Kajutangan streets ( I was born there)
Thanks again,
Humphry Goes (a Indo-Dutchman, now living in France)
