There were two De Vry's bottles pictured in Holiner's Book on Barber Bottles. There was also a labelled bottle called "De Vry's Dander-Off Hair Tonic" in the 10th Edition of the House of Collectibles Guide to Bottles.
The only descriptive notes they gave were that it was clear, and 6 1/2" tall. It's very possible that the two bottles were for the same product, as indicated only on the label. Apparently, the business was located in Evansville, Indiana.
