Seven red and blue pencils from Argentina. They are:
Eberhard Faber Van Dyke 2000. Note the unusual stripe pattern. Hexagonal, oversized.
Eberhard Faber Hevi-Check 6540. Round.
Johann Faber “Alligator” Copiativo. Round red and blue copying pencil.
Pax bicolor. Hexagonal.
Faber-Castell 737. Hexagonal.
Consul Bicolor. Hexagonal.
Eberhard Faber Van Dyke 2000. Hexagonal, oversized.
The Pax and Faber-Castell pencils, the only ones not stating “Industria Argentina”, are the two contemporary pencils. I have read suggestions that the Pax comes from Chile, and the Faber-Castell from Brazil.
My thanks to blog reader dasmarians for many of the pencils shown.
