Today I learned that a houlette is the name of that frame magicians will place their cards in to do rising card tricks. There are hundreds of them still on the market, but I was after the Thayer one mentioned in this ad. After some looking, I think I found an example of both this and the card box from yesterday!
Live Auctioneers has a Thayer lot, and in it contains, "Locking Card Box. Card Houlette. Thayer, Thayer Magic, ca. 1930. Locking Card Box: card appears or vanishes in box. Card Houlette: card rise."
Here is a photo from the site- I think we found our items!...and wow....those are expensive.
