Offset lithography replaced stone-plate printing as the commercial standard through the mid-20th century, making it the dominant process behind most mass-produced graphic work from the 1950s onward. The method allowed for finer color registration and longer print runs than earlier techniques, which is why it became the backbone of concert promotion, magazine publishing, film advertising, and political campaigns across every major print culture. Period originals produced this way are distinguished from modern facsimiles by ink texture, paper aging, and registration marks visible under close inspection.
