We unearthed this test drawing by Bob de Moor for the Tintin story “Tintin and the Lake of Sharks”. The drawing was completed around 1972. Note that the different way of drawing is due to the purpose of the drawing: to serve as a guideline for the animators at the Belvision studios.
For those interested to know how Bob de Moor worked on this and other Tintin animated films, make sure to read Monographie BELVISION – tome 0 – Monographie Belvision – “Le Hollywood européen du dessin animé”, it holds a lot of extra artwork and information.
“Tintin and the Lake of Sharks” (French: “Tintin et le lac aux requins”) was directed by Raymond Leblanc and written by the Belgian comics creator Greg (Michel Regnier). Bob de Moor supervised the film for the Studios Hergé. Note that this isn’t the first time that Greg wrote a scenario for Hergé. Earlier on he had written the scenario for the abandoned Tintin album “Thermozéro” which might now be released after all so it seems.
An album would be published too from the film, albeit in different versions, including a black & white version for which de Moor actually drew the backgrounds as well instead of using just the celluloid backgrounds as is the case in the commercially available album.
