I have a full grid apart from the perimeter. Normally when perimeters convey a message or quotation, the unchecked letters are given in anagrammatic form. What am I missing ?
Bigf, the preamble describes the phrases as 'iconic', so it';s maybe assumed that solvers will be able to spot them. Two of them appeared quite readily for me.
PS I didn't enjoy this puzzle as much as others obviously did!
