There are 30 slides in total. There are pictures of over 10 cars with multiple pictures of several cars from different angles or focusing on a specific attribute of a chosen vehicle. The pictures appear to have been taken at a car show. The slides are incredibly clear and really fun to look at; my photos do not do justice to how these slides project live. One of the sides has a bit of damage from becoming jammed in the slide projector, but it still projects just fine. The slide frame is a bit warped (which is what caused it to jam in the first place).

The slides measure 2.75" square with a viewing size of 2" square.

Some of the included manufacturers include:
I'm not a car guy myself, but from my research, it looks like some of the models (Bugatti 57 and Packard Twelve) were made in the 30s and 40s, so I'm assuming that all or most of the cars are from that era. The slides appear to have been taken either professionally or semi-professionally, and on a picture-perfect day too.
