Background & cover by Patrick Tilley; transfers by Frank Wheeler (Patrick Tilley Associates).
As with all of the first five Panoramas, Waddingtons eventually updated the transfers, having them reprinted in 4-spot colour; here is the original monochrome set cover, followed by the 1971 version:
Patrick Tilley's amazing background remained the same across all versions:
There were two sheets of transfers with every monochrome Panorama, but only with Lunar Base & Ocean Deep were one of the sheets white. The serial number has a "W" (for "White", presumably!) added, so in this case it's "K50W".
The job of recolouring Frank Wheeler's brilliant original monochrome artwork can't have been pleasant. Some sets were more successful than others; this one worked out pretty well.
You can see how the (as yet unknown) artist has converted the characters from the white sheet by using the simple expedient of drawing a thick black border around them…
