Balloon material, rubber on one side, the other a plastic made from Kollodiumwolle (some kind of cellulose; see w:de:Kollodiumwolle) with additives.
- Vereinigte Gummiwaaren-Fabriken Harburg-Wien; formerly Menier-J.N. Reithoffer in Harburg a. E.
- Note: Harburg a. E. is likely "Harburg an der Elbe", now a district in the city of Hamburg. What is the meaning of "Harburg-Wien"? One source to examine further is a history of Phoenix AG (International Directory of Company Histories, Vol.68. St. James Press, 2005.) This company still makes rubber products and sound systems for cars.
