Help with 1890's oversized cabinet

Found this from the following website:

Mounted Prints
were very common before non-curling gelatin silver prints were perfected; the majority of mounted photos in the 19th century were thin albumen prints which needed a stout backing to prevent deformation. Types of early mounted prints included cabinet cards (4 1/2" x 6 1/2") which were mounted on heavy stock, and smaller, thinner cartes-de-visite (2 1/2" x 4"). Mounted prints in other sizes fall into a number of categories, including Imperial cards (9 7/8" x 7 7/8"); panel cards (7 1/2" x 13", 4" x 8 1/4" or 1 3/4" x 5 1/4"); and boudoir cards (5 1/2" x 8 1/2"). Studio portraits from the early 20th century are usually mounted gelatin silver prints; the cardstock backings on which these photographs were mounted were produced in a great variety of embossed designs. Most studio-made mounted photographs bear the imprint or stamp of the studios which produced them.

I guess 8x10" actually do qualify as Imperial.

To my knowledge, imperial cabinets as well as mammoth plates don't have precise dimensions. Imperials are at least twice the size of a standard cabinet, but could be larger than that. Mammoth plates are as the name suggests very large mounted photos, but there are so many different sizes that there is no standard. I would say Leon's Beaneaters photo was closer to mammoth plate, or at least a very large imperial. It kind of straddled the line.
