Here is an older sibling of the current Technograph 777 Artist Tin Set. Judging by the the drip-paint CdA logo on the lid and the squarish print on the pencils, I am guessing it was produced between 1977 and 1998. (Here is a brief official account of the changes to the logo; and here is an article that discusses the typography of the newest one, that I got to know courtesy of La Plume.) It’s interesting how Caran d’Ache completely reversed the order of the words later on, and Anglicized them too; I am personally very fond of the “+SUISSE+” mark on the older pencils.
It seems that Caran d’Ache produced more grades of the Technograph in the past, from 9H to 6B, and so the tins came in two different versions too. The “Technical Drawing” set has grades from 9H to B; the “Artistic Drawing” set is from 4H to 6B. Only the latter survives.
P.S.: A comparison of the back side of the vintage (yellow) and modern tins.
