Abstract: A humidified cigar showcase is provided having a closed cabinet defining an interior with a plurality of partitions such as shelves or drawers. Moist air is supplied to one side of the interior through a supply plenum and withdrawn from an opposite side through a return plenum, creating a horizontal humid airflow through channels defined between the partitions. The plenums are arranged in a rear wall of the showcase to have an inconspicuous profile and so that the showcase interior may be viewed through windowed side panels. The humidity is maintained with a humidistat which controls a fan. The fan drives the airflow, withdrawing moisture from a water reservoir and delivering the humid airflow through the plenums. Baffles may be provided in the plenums to vent airflow more uniformly along the plenums.
