drafting and planning - front cover conventions

for my front cover of my music magazine it is important to use a number of conventions that will make my magazine both professional and unique. some conventions are essential to have  and are found on all magazines. this contains a website URL, date, price and a bar code. i believe that this particular aspect will make my magazine professional. other conventions that i plan to use which are optional is a skyline along the top to form a sort of border which can also act as a sort of cover line. i also may use a PUG or a PUFF to attract more people to my magazine for example a person ma not like reading about their favourite band but they may want a chance to win tickets to see them.
