ESFERA ARMILAR MODELA Construcciones Calleja. Cuarta Serie 9. Hermúa [illustrator]. [n.p, but Madrid, n.d. but ca.
1930-40s. Folding chromolithograph card sheet, 210 x 145mms, folded in four and opening out to 418 x 288mms; card lightly browned, with some minor soiling, small hole in central fold but without major loss, evidence of previous label on verso; presumed without original envelope; a nice bright example of an ephemeral item. A most attractive and scarce example of an educational scientific instrument paper/card model for the use of students, which when assembled forms a three dimensional armilary sphere resting on a base, to measure the rotation of the stars and planets. We have previously handled similar examples produced in Barcelona by Seix Y Barral but which had been stencil cut to ease assembly, as opposed to the present example, which required some careful and skilful cutting. The pieces are labelled in Spanish, with instructions for assembly printed on one board, together with a diagram of the completed assembled globe depicted in a vignette.
‘Instructions: Follow the numbering. Take the two black strips number 15 and place them in the corresponding place in the world. Once the two worlds are joined with their axis, join the circle 15 at the poles. Place the Ecliptic and the Meridian and finally, attach the sphere to the foot or base’.
The present example was produced by the Madrid publishing firm, Editorial Saturnino Calleja (fl. 1876-1958), who produced a vast number of educational cut-out toys on a a variety of themes.
