Parker fountain pen company Parkergrams magazines (3). Parkergrams was Parker’s magazine that went out to dealers and those within the company to let them know about the latest developments, new models, selling skills, repairs and other company highlights. Magazines date from 1930 showing the Duofold pen, in particular talking about the convertible model that can switch from pocket to desk pen. Overall fair to good condition, one example with scarce original paper envelope.
