This paper presents part of the research carried out on some architectural drawings associated with industrial design in Spain during the 50s. The selection of these was made in the context of the research team in which we participate about the SEDI group (Society of Industrial Design Studies) and all of them come from the COAM¿s file. These are professional drawings by Javier Feduchi Benlliure (1929-2005), among them some of the elaborated ones for the project of pavilion for the VIII Trade Fair of Bilbao in the year 1957. We also present unpublished drawings prepared for other fairs or exhibition elements. Through these graphical analyses, we will document their participation in the elaboration of architectural drawings linked to industry and industrial design, as well as the graphic characteristics that accompany the way of understanding and representing these types of projects.
