The Arcadian observer
The Arcadian Observer is a periodical published in 1918 at Arcadia, California, by the U.S. Army Balloon School for its trainee officers and staff during the First World War. The surviving picture is not from its aeronautics content but from an advertising page, showing a Hydro-Pura washing powder notice beside a Cline-Cline Co. store advertisement with bold serif lettering, rules, and a boxed logo. A designer could take from it the period's dense newspaper-style advertising layout, with mixed typefaces, hairline dividers, and a centred trademark block.
