Pictures designed to start illusion (13)
I believe the answer is:
illustrations
'pictures' is the definition.
(I've seen this before)
'designed to start illusion' is the wordplay.
'start illusion' can be anagrammed to 'ILLUSTRATIONS'.
Though, I am unsure how the anagram is indicated.
Can you help me to learn more?
(Other definitions for illustrations that I've seen before include "Pictures (in a book)" , "drawings?" , "Examples" , "artwork" .)
