The wood box, with the glass face, was known as an observation hive. As this one was, they could be closed and moved around, or they could be connected to the outside, I have seen permanent installations that were five times the size of this. I have written before about my father and grandfather being beekeepers. I displayed bees one year at the county 4-H fair. Having live bees in the exhibit hall made a few people nervous, but came off without an issue. I still have the best in class ribbon from that year.
Have you seen an observation hive?
