Bold, simple, recognizable from across a " + "room. Drawn in colored pencil and gouache with thick confident " + "strokes and high tonal contrast at the subject's center, gradually " + "softening to nothing at the periphery.

Incidental product or manufacturer text " + "already physically belonging to a depicted object (a SONY mark on " + "the body of a vintage camera, a small disk-brand logo, the printed " + "model number on a floppy's metal shutter) is acceptable when it is " + "NOT the institution being illustrated. Letterforms may appear as " + "illegible scribble-gestalt where the form of letters is part of the " + "object's character (a stencil sleeve, a typed page, a chalkboard, " + "the rhythm of engraved name-bands on a plaque) but they must NEVER " + "spell readable institutional names. The institution's identity is " + "carried entirely by ICONOGRAPHIC EMBLEM, FORM, SILHOUETTE, COLOR, " + "and ERA (the elephant, the temple, the pixel-burst, the hexagon, " + "the inverted stoop, the brick arch, the brass seal). Muted natural " + "palette (terracotta, sage, ochre, dusty pink, slate blue, brick red, " + "warm grey, oxblood, brass). Square 1:1 composition. The subject: ";
