These are from a book called
A Water Tour of Seattle, published in 1961 by Child Tourist Publications, Inc. These terrific illustrations by Merrill Grant put me in the mind of the
Miroslav Sasek This is... series of world travel picture books.
David Moore first showed me this book and I later found a used copy. But, I haven't been able to find out anything else about good ol' Merrill. If anyone knows more about him (or her), please write!
