Hi Darryl - I think the best hope for another copy is going to be second hand. I think the book is out of print - my late Mom contacted the publisher to get my copy about 15 years ago, and the one I have was found in a box somewhere...

You could try and contact Struik, the publisher, of course.

I did a quick Google search, and a copy shows up through Alibris (a web site that represents second hand book sellers) for a whopping $120!

Good luck tracking it down!
