My most recent example of the Master Photoguide dates from 1981, and I don't know how much later they were produced, but I would assume that they stopped making them by the late 1990s. Back in the day, it was (and still is) a good thing to have in your camera bag. If you are new to manual film cameras, the Master Photoguide is an easy way to have a lot of information at hand.
There were subtle changes in the Master Photoguide over the years, as camera and film technology changed. I like the older ones that actually had the filter gels in the page. That makes them useful for seeing how a filter changes how the image looks to your eye. The guide also has the "filter factor" chart to adjust your exposure for a given filter. If you have a meterless camera such as a Nikon F with a plain prism, a Kodak Retina IIa, or a Yashica A TLR, the guide is quite handy.
To me, the genius of the guide is that all of the subjects are located by the tabs at the edge of the page. A quick looks takes you right to the appropriate topic. Secondly, the guide has the essential information that a photographer needs without the fluff that may be found in a much larger book.

I did a brief look online, and the Master Photoguides now sell for more than they did when new. They are often most encountered in old camera bags and thrift shops, so keep your eyes open for the various editions. The most recent one has a silvery cover, and is easily identified.

The daylight exposure guide looks suspiciously like it is based on Sunny-16. Yes, it is!
