On the left is the US pressbook cover for the movie,
The Haunting (1963) with Julie Harris. And on the right, an Australian daybill for the UK horror-comedy, called
Horror Hospital (1973), with Michael Gough.
What is seen is the obvious "lifting" of artwork that was created 10 years before, for a completely different movie, and using it on this daybill. Even the letter "H" of both the word "Haunting" and "Horror" is almost identically copied, font-wise (as well as its placement).
One can almost make out the masked-out (covered over) word, "The" above the word, "Horror," on the daybill, as well.
