A vintage embossed cardboard advertising sign for Smithsonian Trusses, likely dating from the late 19th to early 20th century. The sign features a black background with raised, cream-colored lettering. The brand name Smithsonian is rendered in a large, flourishing script across the top, while the word TRUSSES appears in bold, serif capital letters below it. A decorative flourish separates the branding from the slogan at the bottom. The slogan reads MAKE WEAK ABDOMENS STRONG AND RUPTURED ONES WELL in all-capital block letters. The sign is constructed from heavy cardstock and includes two small circular holes at the top center for hanging. The reverse side shows the indented ghost image from the embossing process.
