There's Nothing Holdin' Me Back Shawn Mendes
Martin and Su want to create a gallery that includes all of the album covers from the Now albums to celebrate its 30th year.
Since 1983 there have been 84 albums and Martin and Su want to gather them all into one gallery.
Take a look below to see how many Martin and Su have and which ones are missing.
If you have any of the absent album covers, you can upload your picture to the Heart Essex Facebook Page, or tweet us @heartessex.
Thank you to everyone who has helped us so far!
