If you are a budding Graphic Designer these should interest you. The Pantone Color Guide for easy on-the-go colour reference, everything from design inspiration to press check. Am selling my vintage 1992 edition, Coated version, so it cannot be trusted for high-end commercial print work but ideal reference for the Graphic Artist and sure beats the current online price of $300. Selling for $80.
The PEAK Lupe (aka Loupe or printer's magnifier) model 1962 is also from the 90's, hasn't changed in 40 years so still ok for checking CMYK print registration. Grainger wants over $70 for this 15K model, am selling for $40.
Buy both Pantone and Lupe for $100 firm.
