Old Borneo Map

I was spring cleaning my study yesterday and in one of the envelopes that I nearly threw away was this map of Borneo. I must have ordered this quite a while ago and have never got round to framing this. I don't know how old this map is but judging by the data should be around 100 years old at least.The boundaries are not marked so that means Rajah Brooke have not arrived yet to take over Sarawak
