Do You Know The Problem With Buying 1970s' Editions of Georgette Heyer Novels?

You end up with covers like this:

(From the 1970 edition of Sylvester.)

Or this:

(From the 1972 edition of Charity Girl.)

Or this:

(From the 1971 edition of Faro’s Daughter. Yes, I do know why she has him tied to a chair. No, I’m not going to tell you.)

Or my personal favourite, this:

(From the 1973 edition of The Toll-Gate.)

I know Georgette Heyer is known as much for the minute historical detail with which she invests her plots as she is for the fact that the plots are, essentially, all identical.

If only her illustrators showed some of the same fascination with historical minutiae.

Or am I wrong in thinking that Regency England was not so much the era of the false eyelash?
