Item 8 is Albert Eduard Brockhaus' Netsukes, published in 1924. Originally published in German in 1905, this is an English language edition of a work written because Brockhaus feared netsukes would fall into oblivion. Twelfth Street points out that this book is still considered "a netsuke bible by collectors." But, what is a netsuke anyway? It's a miniature hollow carved sculpture, invented by the Japanese, that could be hung from your garments by a cord to carry personal belongings. Think of them as a purse for men. $135.

Item 97 is a history of the fabulous gem show held every year in Tucson: The Tucson Show. A Fifty-Year History. The show began in 1955, and author Bob Jones has attended every one since 1960. Thousands of people who ply the gem trade attend every year. The book includes photographs of the exhibitions over the years. $40.
