Carbon transfer prints are basically comprised of pigment encapsulated in hardened gelatin. This makes them physically much more like some types of painting that consist of a colloid plus pigment.
One problem you may have with exhibiting carbon transfer prints without glass is expansion and contraction of the print. This problem is especially bad with prints on thin papers when exhibited in rooms where the RH varies a lot. With this type of print and conditions it may be better to mount the print on an archival matte board, or on a surface like Di-Bond.
