Blue pencil was the famous pencil used by Portuguese Salazar’s dictatorship censors. This photograph which presents the blue and red pencil (from the same Viarco factory) thematically introduces confusion as a response to the invitation to produce a new piece of 20x20cm in response to the theme Mono, and paying hommage to the art group based in Coimbra, Grupo de Coimbra Cores, CAPC 1976/78.
