Akin to the above approximately 5x7, some double-wide ones are about. Later albums are about 8x10 and have space for our smaller images but are meant for the later cabinet cards.
Empty ones are commonly available (dealers dump the images and sell individually).
Quality varies and even the perfect ones suffer from dry rot, bugs, and foxing.
I personally would raid the scrapbooking section/frame store and make a reasonable facsimile of archival materials. This preserves the original album from more wear and tear and your images from a less than kind environment.
If you do find a good one, treat it to a good archival cover and tissue between the leaves to preserve it.
