This blue bookplate is featured on the inside front covers of both volumes of The Moffat Tunnel of Colorado by Edgar Carlisle McMechen. The stately set was published in 1927 by The Wahlgreen Publishing Company of Denver.
I purchased it today at The New Street Book Shop in Bethlehem, Pennsylvania. It's a beautiful independent bookstore tucked into downtown Bethlehem and, sadly, it's going out of business in less than a month.
The quotation featured on S.A. Lavine's bookplate — "Neither a borrower or a lender be" — is from Shakespeare. Polonius says it to Laertes in Hamlet. The full quotation is:
"Neither a borrower nor a lender be,
For loan oft loses both itself and friend,
And borrowing dulls the edge of husbandry."
