New York 1918 Sea Wax Company Rheumatism Letterhead 8.5 x 11

This 1918 letterhead from the Sea Wax Company of New York City reflects early twentieth-century marketing of proprietary remedies during a period when patent medicines and therapeutic claims circulated widely.

Businesses promoting treatments for conditions such as rheumatism often relied on direct correspondence, printed literature, and physician referrals to reach potential customers. Many such products were derived from natural or marine sources and presented with quasi-scientific explanations to support their use. The regulatory environment was evolving at this time, but promotional language still frequently emphasized broad effectiveness and minimal risk.

The document features a printed header reading Sea Wax Company with a seahorse logo and address at 7 East 42nd Street, New York City, dated December 16, 1918. The typed letter is addressed to a recipient in Reading, Pennsylvania, discussing the product’s composition, derived from sea moss, and its intended use for relieving rheumatic pain. The text includes cautionary language about variability of results while still promoting its benefits. The letter is signed at the bottom, presenting a complete example of period medical marketing correspondence on original stationery.
