And here's the original cover from 1966:
With the 1971 edition, the standard flat-colour half-frame has been slapped over the artwork, with particularly absurd consequences in this case — it covers the top half of Gulliver's face.
As with the other 4-spot Panoramas, these transfers were printed using Red, Blue, blacK & White. Sheets K99A & K99B:
In an interesting development, Letraset reprinted this set much later for Gillette as part of the Kalkitos range.
However, you will notice a few changes; the sides of the background have been cut off, & of course the artwork has been completely (& rather crudely) redrawn — probably traced from the original.
This applies to the transfer sheet as well; you can have fun relating the Kalkitos transfers to their Panorama counterparts.
