I couldn't help noticing the basic similarity of the blue rocket fin and base on this old 1960 German magazine* to that of the Project SWORD Apollo Saturn toy from 1967**.
I've put them together for you. Toy on the right.
What do you think readers?
*Fluech der Vergangenheit = Curse of the Past.

** the earlier 1963/4 versions of this toy by Tomy/ Sears are partly blue.
