LTR Federal Optical
LettError · Erik van Blokland, Just van Rossum

An optical-size companion to LTR Federal, drawn in the style of steel-engraved banknote lettering with high contrast and full-length serifs.
About
Part of LettError's Federal family, this optical-size variant is designed to complement LTR Federal Regular with the shading and high contrast characteristic of Federal Bureau of Engraving and Printing lettering. The design is not a literal revival but an interpretation of that formal tradition of steel-engraved type. It sits within a broader Federal ecosystem that includes LTR Federal Bureau and LTR Federal Reserve Note.
Classification
High-contrast, steel-engraved style with serifs from top to bottom, placing it firmly in the display serif category with an engraved or intaglio subcategory akin to traditional banknote lettering.
