Rumph Catalog
This catalog is listed on the Rumph.com website as possibly being one of a kind. Well, since I have one, that isn't so, but I expect they ARE very rare. My copy unfortunately does not have a cover. From the Rumph.com page I can see that the front cover is the same as the Magic Age of Rumph book, so I used a modified version of that here. However there is an inside cover that can be seen there. I will transcribe what it says. If there was something on the back interior cover, I don't have it.

     At seances and incantations down through the ages, Rumph drank delights from these very pieces.

     Rumph is white not black magic. Therefore only positive things are forbode as you partake your hot and cold pleasures with Rumph.
