A few minor brags from a FOL sale..

In the case of the early thrillers, I would put their scarcity down - in
part - to the fact that they are much more collectible than the romances,
which I imagine are scarce - at least in part - for precisely the *opposite*
reason - secondhand booksellers would turn them down, saying no one wants to
buy those old romances, and they'd end up just getting chucked out.

Georgette Heyer's romances may or may not be widely collected in an antiquarian
sense, but they still have plenty of fans. They're silly books, but *good*
silly books, if you know what I mean.

I think there are a lot of people who get a kick out of collecting early
thrillers in general, so there is probably more competition for fewer copies (I
don't know how well Heyer's thrillers sold, but I have never heard of their
having a tenth of the popularity of the romances).
