Dated : Kamp Columbia 3-8-45
This digitised copy of the original booklet provides a satirical overview of the people at Camp Columbia. The author most likely uses a fictional name: Prof. Dr. K.F. Pescator. Through descriptions of flora, he portrays the various military and civilian ranks and positions of the personnel.
Perhaps it was presented during a performance, and it might indeed have been for the Netherlands East Indisch Red Cross, as mentioned in the booklet. The booklet was donated to the CCHA via the Netherlands (Bas Kreuger).
Any further information is very welcome.
