H. RIDER HAGGARD The Wizard. Collier, circa 1920. Unusually nice.
THE WIZARD by H. RIDER HAGGARD. P.F. Collier & Sons. About 1920. I am guessing on that, but it is from the period after the first editions had appeared (this one was first published in 1896) but of the period when Haggard was still popular enough that matching sets of his works were available.
