I've been buying disks and tapes of old commercials for about a decade now. This three disk set will likely contain a fair number of the ads that regulars to public domain and retro media sites already have bought before now. But one nice plus this collection has, which the others I have had definitely do not, is a chapter break for each commercial. It's not a complete index of every commercial. It's the ability to hit your remote's chapter advance button and move to the next commercial, one ad at a time, through each disk. This makes cueing specific ads up, or skipping items of less interest to you, much easier than any other collection I've seen. (Most disks on the market seem to be made up of bulk transfers of old ads in 30 to 50 commercial chunks. Much of this material came straight from an online archive of public domain material in this form, and until now, no one has troubled to break it up for easier use.)
The video quality is of a very wide range, and some of the images are a mess. But anyone with a passing-to-serious interest in old commercials, or pop culture from the 50s to the 70s, should pick one of these up for general purposes. It pretty much "retires" about half the commercial sets I have bought up until now.
Note: There's also a section of Drive-In movie promotional films ("Come by our snack bar..."; "Enjoy our mouthwatering hot buttered popcorn...") at the end of the third disk. That was a pleasant surprise.
