Dear client:
Thanks for your inquiry re: magazine headline style. I have endeavored to adhere to the proper style for the documents you have sent me which had headlines. The standard rule applies to magazines that all words save for prepositions and appositives are rendered in upper case. That said, some publications apply some changes, of which I might not be aware, to standard style. Should you receive any feedback pertaining to this I would welcome such information; it will help me should the matter come up in future documents.
Thanks again for your inquiry; I hope this has been of help.
