The first is a softcover copy of Louise Brooks, by Barry Paris. This 1990 edition is out-of-print, and second-hand copies can be found for only a few dollars. Nevertheless, this seller is asking $4,999.00 for a mint copy. Go figure.
The second is a copy of the Louise Brooks edition of The Diary of a Lost Girl, which retails for $24.95. Here, this seller is asking $224.55. Wow!
