My grandmother, when she died, had about a dozen rolls in a drawer - one of the rolls had a picture of my 4th birthday party! If it is all industrial like the sample, it could be a job that was cancelled and the photographer just didn't see the need to pay for the developing and forgot about them.

Still, if you have the money or time to develop them, there might be something really interesting. I did 40-rolls of B&W for a guy in exchange for a 5x7 enlarger, some very interesting shots.
