To me, this is a previously unseen packaging variation of these place cards meant to hang from the top of a glass. These same designs were issued by Beistle as early as 1918 in an enveloped set of six given stock number 584. In that earlier set, the contents distribution was three witches, two cats and one ghost. In this larger set, the contents distribution was six witches, three cats and one ghost. So, although the numbers are different the relative scarcity remains the same - the ghost being the hardest one of the trio to get. I felt the ending price was pretty high - certainly good news for the fine seller. (I’ve done business with this seller and look forward to doing more!) Looking at the prices obtained for the singles from this set that he sold in other listings, their prices, too, were dazzlingly high.
