I'll say it's a Planet of Adventure

From this heartfelt page:

Should a literary masterpiece published in America surrender both its title and content decades later at the whim of contemporary British gutter slang? I cannot imagine it. Surely the least of Jack Vance's work will long endure past the demise of off-color terms in any local dialect, even that of Her Majesty... One might very well declare that I strongly overreact to this work having been retitled as The Wannek.
