There's certainly a few seemingly anomalous editions of McBain books knocking about - some strange combos of 87th Precinct novels from different eras in one volume, for instance. Today I stumbled upon the following hardback:
This is the rather bizarre combination of a 1987's "Puss In Boots" - not an 87th Precinct mystery, but the seventh of the Matthew Hope novels (Hope, McBain's Florida-based lawyer does come into contact with the 87th Precinct in his final outing, The Last Best Hope in '98.) - and 1958's "Lady Killer" which we reviewed on this podcast.
The cover of this hardback, published in 1988 by Guild Publishing, is certainly of its time - nice stark, nearly neon, lettering and a cover that probably has some resemblance to the plot of the Matthew Hope novel, but not at all to the 87th Precinct story.
If you're desperate to experience this dual-book curiosity yourself, then I spotted it the British Heart Foundation charity shop on Bold Street, Liverpool. Don't all rush at once.
