Original post here. This image was researched by Bacchus at ErosBlog as part of the “Γ commission.” The research was originally published at Hedonix as “Γ 031 – The Battle For Earth. Here is what Bacchus found.
The “Don Lawrence” signature on this image refers to the British comic book artist perhaps most famous for his Storm series of comic books (22 volumes over 25 years). According to the artist’s official website (where a fairly detailed biography is also available), this image is from the fifth volume of Storm, entitled The Battle For Earth, written by Dick Matena and appearing in the Dutch serial weekly Eppo ##23-43 in 1979.
There is an authorized 2D-to-3D conversion of this image available on Flickr. A gallery of large-format artworks from Storm (including this one) may be found here.
