There are at least a few other scans of this or essentially the same book. This UCLA - University of California- copy seems to be the cleanest.

The font used in another UCLA edition is challenging because the lower case "s" looks like "f". I feel like I’m lisping when I’m reading.

There appears to be bleed through or transferring of brown stains that’s fairly uniform throughout. It has 22 credited woodcuts with some looking better than others. Artist’s prints degrade over the series but I don’t know if woodcuts degraded over print editions.

This University of California copy seems to be the cleanest and easiest to read, was published 15 years later and is also highly illustrated with uncredited woodcuts. I did a side by side comparison of the illustrations I find interesting.
These are very clear and precise yet make me hope the original illustrator was well compensated.
