Vintage Chevrolet Dealer Service Chart Set 1960s GM Garage Shop Sign Decor 6pc

Up for sale is a fantastic, complete matching set of six (6) vintage Chevrolet Super Service promotional educational charts. Distributed by local Chevy dealerships back in the 1950s/1960s, these charts were originally sent to high school shop classes, trade schools, and local garages as practical mechanics' reference guides and branding tools.  Because individual sheets from this series were often separated, lost, or ruined in greasy workshops over the decades, finding a complete collection of six matching panels together like this is incredibly rare!  Included in this 6-Piece Set:   * Our Country's Formative Years: A historical map and portrait layout.   * From Fibers to Fabrics: A detailed textile and manufacturing process guide.   * Household Measurements & The Circle: Fundamental geometry and mathematical conversion layouts.   * Hand Tools for the Home: Visual guide to hole-boring tools, bits, braces, and clamps.   * Threading Tools and Materials: Comprehensive specification diagrams for Taps and Dies.   * Screws, Bolts & Pipe Threading Data: Essential hardware sizing charts featuring the iconic Chevrolet Super Service Bowtie Logo.  Condition Note:   * Sheets: 6 individual, separate sheets.   * Overall Condition: very cood clean condition. A little ink scribble on one. Unbent.
