For the first thirty years of its history, the Wagner trademark consisted solely of the word "WAGNER", incised either in a straight line or in an arc, and with the addition below it of "SIDNEY, O." at some point. Various combinations of straight and curved lettering were seen, as well as the moving of the trademark from the 12 o'clock position to the center, and back again.
About 1914, Wagner began to brand its cast metal cookware products as "Wagner Ware". Pieces previously lettered with an arched "WAGNER" above a straight "SIDNEY" with an "O." below were seen having patterns modified to insert the word "WARE" in between Wagner and Sidney.
From the cobbled together Wagner Ware trademark would come the seeds of inspiration for what would ultimately become Wagner's most iconic trademark. The single, large, fancy "W" for both words, along with "SIDNEY" and "-O-" standing for Ohio beneath would become known as the "stylized logo".
The stylized logo was seen moved around on skillet bottoms, just as the block and arc trademarks had been years before. It would finally settle at the typical 12 o'clock position and stay there until its last use.
At some point in the stylized logo's history, shortly after the introduction of the smooth bottom skillet, it would appear, an interesting variation occured. The wording "CAST IRON SKILLET" was added in a downward curve at the 6 o'clock position, and the stylized logo was surrounded by a border which happened to form a wedge shape. This would come to be known as the "pie logo", and skillets so marked would become some of the most collectible Wagners. Pie logo skillet production appears to have only spanned a ten year period, and the reason for its discontinuance is not known. Before an apparent replacement of patterns, examples are seen with ghosts and artifacts characteristic of "pie logo" skillets.
After 1959, the last year of production of what is considered collectible Wagner cast iron, the "SIDNEY -O-" was removed from the logo. This perhaps reflected that casting operations had been moved to Cincinnati by current owner Textron/Randall, or at least were no longer confined to Sidney. The subsequent addition of succeeding parent company General Housewares Corporation's logo after 1969 would also see a 180° flip in the orientation of the markings on skillet bottoms.
Using this table, the approximate time period of manufacture of a Wagner trademarked skillet can be determined.
