These attractive, colorful miniature fountain pens from the '30s came in a tremendous variety of patterns. Being bulb-fillers, many of these pens have transparent or translucent barrels; most are equipped with 14K #0 nibs, though they were sold with gold-plated steel nibs as well. Facetted versions – miniature Dorics – were also made, as were desk pens and matching pencils. World's Fair collectors will want to keep an eye out for the specially-imprinted model made for the 1933 Chicago Century of Progress exhibition.

The picture above should give some idea of the size of these diminutive pens; they typically measure around 9.7 cm (3 13/16") long, closed.
