Per Craig Schenning:
I believe this plate began its life back in the 1940s and Indiana made it all the way through the 1980s, maybe even a bit later. I have no doubt that you could find this with a variety of domes/covers. Mine is a more recent make and has a glass dome, but it was also sold without a dome, simply as a cake plate. And no, sorry, it is not in my current book.
