Possibly forces tiepin into a book illustration
I believe the answer is:
frontispiece
'a book illustration' is the definition.
'frontispiece' can be an answer for 'illustration' (I've seen this before). I am unsure of the 'a book' bit.
'possibly forces tiepin' is the wordplay.
'possibly' indicates anagramming the letters.
'forces'+'tiepin'='forcestiepin'
'forcestiepin' anagrammed gives 'FRONTISPIECE'.
'into' is the link.
Can you help me to learn more?
(Other definitions for frontispiece that I've seen before include "Illustration facing a book's title page" , "Picture at beginning of book" , "Plate" .)
