A cabinet is an albumen photograph that is glued onto a roughly 5" x 8" cardboard mount. They were among the most popular forms of photography from the 1870-1890's.
The second part of your question-what is a vintage photo- is a little tougher because by definition it covers all original early photography. I guess I would define "vintage" as an early, first generation photo, such as a wire photograph. Often, the negatives were reused at a later date. I wouldn't consider that vintage.
