With these items, one simply has to be patient and keep checking back. And be prepared to spend around $250, unless you just happen upon an eBay listing by someone who isn't aware of the going rate for these catalogs.

Alphabet Thesaurus Vol. 2 seems to be the one you can find on Booksold.com

For a complete overview of all the fonts produced by Photo-Lettering you only need these two catalogs:

• Photo-Lettering's One Line Manual of Styles (1971)

Index to Alphabet Thesaurus vol. 3. 2 and 1 plus new fonts never shown before by Photo-Lettering. For a long time I thought the One Line Manual was the last time
Photo-Lettering showed new fonts. In 2006 the late Bob Alonso, who worked for Photo-Lettering for over 33 years, wrote me in an e-mail:
“The last publication Photo-Lettering put out showing new fonts was the supplement to the one liner (probably very hard to find). There was I believe a few more supplements put out after that but they were not showing any new fonts just trend setting Ideas and maybe some existing fonts that were digitized for the MAC.”

• Supplement to Photo-Lettering's One Line Manual of Styles (1974)

Booklet of 24 pages with 22 pages showing new fonts. The lay out is exactly the same as the One Liner. Since Bob Alonso brought this book to my attention I’ve been looking for it. Last january I finally managed to purchase a copy, so it took me 5 years to find one!

I don’t know if you already own copies of these books, but if not, I recommand to buy them if possible!
