This nice little grouping is interesting. Beistle produced and sold these from 1927 through 1931. There were four designs overall. This listing is missing the one I like best, which shows a witch wearing a skull laden robe stirring a cauldron. The honeycomb sections that have separated from the main bodies, ostensibly due to dried glue, should be easily re-attachable. The extant glassine envelope is dull and shouldn't be much of a factor in what you may wish to bid on this lot.
