Books of the older variety

The last two gold books for sale.
‘There was gold in the river’ by Frederick Miller 1946 It is about gold in Central Otago illustrated and a good read.
‘Forbidden gold’ by Will Lawson set at Terawhiti station unsure of date of publication valued at $55.
I would appreciate $40 to $50 for the pair. P&P included unless you want to pick them up.
