ESFERA ARMILAR TRABAJO MANUAL INSTRUCTIVO de fácil construcción para los alumnos. Barcelona, Industrias Gráficas Seix Y Barral Herms., S.A.. [n.d. but ca.
1910-20s?.]. Small folio; two chromolithograph card sheets, 320 x 237mm, with 15 die-cut pieces (still in their original frames), outer frames a little browned with some minor soiling, but otherwise very good; both sheets found within the original printed publisher’s illustrated and printed envelope, 328 x 245 mm, lightly sunned and foxed, but otherwise clean and bright; offered together with a variant issue. A most attractive and scarce example of a disassembled scientific instrument paper/card model, comprised of two sheets of chromolithograph printed stencil-cut card, which when assembled form a three dimensional armilary sphere resting on a base, for the use of students of geography and astronomy. The 15 individual parts are still secured within their original frames as issued, ready for assembly, and comprise hoops representing the equator, the tropics and other celestial circles. The pieces are labelled in Spanish, with instructions for assembly printed on the outside of the envelope, together with a diagram of the completed assembled globe. As revealed by a series of further advertisements, the present sphere was one of a number of similar educational aids and models produced by the publisher.
Offered together with a variant instrument, housed within an identical ‘Esfera Armilar’ envelope, but the two stencil-cut sheets having nine individual parts (which we believe to be complete), the main part of the sphere being a translucent ‘sun-dial’ marked from 1 - 24 and E to W. We have been unable to find any other example. Envelope more browned and soiled, with small nick at right hand margin, with small tears along flap but still good.
