With letterpress instructions by Calman on a separate slip at the right. The sky image 33 cm in diameter; the whole chart with the letterpress slip as mounted 49 x 61.5 cm. A string with a bead serves as a pointer for aligning the scales in the stationary and rotating parts. Coloured by a contemporary hand and mounted on contemporary boards covered with marbled paper, apparently by the publisher, so that it can be folded in half for carrying.

In the plate of the star chart itself is engraved, “Auct. J. Stampioen. ‘t Amsterdam by Iochem Hasebroek” but Hasebroek’s name is larger and in a different style than the rest of the lettering, and one can see traces of an earlier name under it. Although the older name cannot be deciphered, one can see that “Hendrick Doncker” would fit (with traces of the h and Do, and marks where the ascenders to the d, k and k would have been), making it clear that the present chart is printed from Doncker’s original plate. Calman advertised his Amsterdam boarding school for calligraphy, mathematics, etc. in 1722, and Hasebroek (1682- 1756) is recorded as a sea chart publisher and instrument maker from 1714 to 1743.
