More often encountered as G[.] F[.] Maine -- I'm not sure what the convention was with full stops after initials in his time. He would have cared, being an editor of note. You may well have come across him without realising it.
Wiki washes its hands of him with a snub of a sentence: Most of his work was leather-bound, and published by Collins. Who can add more?
This is probably the worst idea for a thread I've ever had. I did once start a thread about Dinner for One, and it got no replies, but in theory it might have done.
It was the same with the Champagne Breakfast thread I started.
Anyway, your Mr Maine edited a generally heart-sinking selection of books.
I'd have thought that one was a sure-fire winner. Both champagne and breakfast enjoy widespread popularity.
I don't think anyone wanted to admit that such dissipation had ever figured in their wholesome lives.
I was thinking of him in relation to his edition of Wilde that I treasure, although it is falling apart, alas. It is or was a hardback printed with the paper of the immediate postwar years. In Maine's biographical introduction, the reader is informed of the basic structure of Wilde's life, from his early fame to prison and afterwards. And although it referred to his ostracism from society, there was no mention of the crime for which he was imprisoned, or the circumstances leading up to the trial for that matter.
Also, some of the Greek quotations were printed with misprinted letters, or in extreme cases upside-down.
I can understand why you would treasure that souvenir of the great post-war paper famine.
Those War Economy Standard books were often lovely little craft works. Thin paper, nicely tooled bindings, so easy to slip into a pocket.
