Vintage photographs can be a great collectible and wonderful props for associated retail.

The fashions of the era the photograph was taken, the people, places, and props can all be fantastic reminders of days gone by. Simpler times. Snapshots are great for this. 

Professional Weddings, Class, Family, Group, Occasion, and Portrait are all interesting photography subjects.

I have many vintage photos in my store catergory Vintage Photographs. They start about from the 1920's and run later into the 1950's.

Some of my cabinet photos are actually earlier than 1900.
