This devil Lightning Wumpus seems to be in very nice condition, indeed. Typically, these are pretty well thrashed given their size, fragility and many pointed edges. I haven’t seen one in this stellar condition in some time. The partially extant glassine envelope (The seller incorrectly describes it as plastic.) is seldom seen and should act as a minor accelerant to the ending price. Beistle produced this design, as well as three others, during the interval of 1929-1931. (You can see the others on page 146.)
04/12/Update: This sold for a strong $1,009.
