It sounds a lot, consider it a fine piece of art in it's own right and I don't think you'll lose your investment over time... The reprint by M$ does not do this original large format version which is crisp and sharp.
It's a beautiful book. He also signed it for me, in case that's a thing you value.
I'd love to know how different his reprints are the the originals. I've seen one from the original run, and they looked the same to me. (But it had been a while.)
I wish it were $40 though. A $100 is a bit outside of my impulse purchase zone.
