Albert Gerrer S.A. Mulhouse, catalogue n°4:
"The A.G.M. Glass Sign.
It holds its place, it is unalterable, and is not affected by the weather. Being always fresh and clean, it is of great value, its brilliancy is incomparable and attracts attention to the place and at the time desired.
It is economical, as its almost unlimited duration permits the amortization over a great number of years. Its mounting and upkeep require no expense.
It is of the first quality; its appearance, its brilliancy and its high style, give it the benefit of the best places without expense.
Our glass signs are essentially of French manufacture; they have been adopted by the elite of the industry, who honour us with their custom. This is the modern advertising. You will find that it is widely employed in other countries for many years past, by the leading houses."
(Excerpt from A.G.M. catalogue n°4, circa 1935)
