The poster measures approximately 27 inches wide by 10 inches tall and represents the only example I have seen in 25 years of collecting vintage Disney memorabilia.
The introduction in the catalog states:
"The Oak Rubber Company started the manufacture of toy rubber balloons in 1916. Oak Balloons quickly established a reputation for a new degree of toughness, greater elasticity, brighter colors, attractive designs and novel variety."
The company used "milled," virgin, liquid latex rubber in their production process. Given the fact most of the rubber used in America at this time came from the South Pacific, I am not sure how this company fared during the war, when rubber was rationed and the Japanese occupied many rubber producing regions.
The 48-page catalog contains nine full-page Disney related advertisements and six additional pages where a Disney product is featured with other balloon products. Besides the following images, there are also two full-page ads featuring Snow White themed balloons.
Package for the Stratosphere novelty.
The Stratosphere Balloon novelty consisted of a balloon (9 - 10 inches tall when inflated), and a cardboard die-cut balloon basket. The basket featured the likenesses of Mickey, Minnie, Donald and Pluto. Hard to see in the scan, but Donald is reading a book about air sickness.
