One problem with dry transfers is that they were most successful with boys. Letraset were aware of this, & this set is clearly an attempt to appeal more to girls — although whether or not it achieved that aim is unknown.
As with the Haunted House Panorama, the transfer sheets have been printed in two spot colours — black & white — with the figures (although not the text or registration marks) on one sheet being all white. It's reasonable to assume that the Haunted House & Fairy Tale Landscape transfers were printed together. If you examine the positions of the registration marks you can see that the horizontal black strips are 15" apart (one above the other), & the cross-hair marks are 12" apart both vertically & horizontally.
