I'm getting interested in Thai fonts now, and would like to look at some specimen books. I've already found แบบตัวพิมพ์ไทย (Thai Fonts) in digital form (PDF) and am wondering if there's any place I can get it in paper form before printing it out myself. I'm also aware of Theppitak Karoonboonyanan's work maintaining the NECTEC fonts for Linux.
But what I'm really interested in is older, pre-digital specimens of high-quality Thai printing.
I have one gem already in my collection, Débuts de l'imprimerie en France: L'Imprimerie nationale. L'Hôtel de Rohan (see p. 160 for the "Siamois"). I have some other lower quality samples, like a book on printing "Foreign Languages" from the US Government Printing Office, but what I'm looking for is the good stuff, quality metal from the pre-digital era. Specimen books or just well-printed books are all welcome -- I want to do my averaging trick on the smaller sizes of text, and I am in particular interested in optical sizes for Thai, as I think those small loops and curlicues could be more robust in smaller sizes and smaller and more refined in larger.
Examples of excellent calligraphy and penmanship are also most welcome.
Any help would be greatly appreciated!
