			No way I read Japanese Frank, but I can still use the print ads in their publications to help date guitar literature.
So for example, I have a print ad from a dated Japanese publication like Japan Music Trades:
This ad is typical in that it pictures both a guitar and amp with prices. The first thing the ad tells me is that ELK was still using the script logo in 1968. I can also look for the same equipment in ELK brochures to put a date on an undated brochure. If you find the same equipment in a brochure selling at the same price as the ad, you can be pretty confident they are from the same year. If you find the same equipment in the brochure but the price is a little higher, you can assume the brochure is a year or two later than the ad.
Of course, it's still guesswork, but it is better than nothing. The reason I say it is slow work is that late 60's - early 70's Japanese music publications don't show up that often, and when they do, they are typically expensive.
