This is a magaazine advert promoting Florence + The Machine's new album and tour. They have simply placed the album cover in the middle of an A4 page and added the band name at the top and information in white font, centered.
This is Fleet Foxes' promotional magazine advert. They follow exactly the same conventions as Florence and The Machine's.
White Lies' promotional magazine advertisment is very similar but the album cover is the whole background of the page.
