Desperately looking for help with HIDING header image on one specific page
 

1st I love your theme. I am lacking programming skill and this is awesome for me to make webpage for my businesses.
MY PROBLEM: I made a splash intro for a landing page but I cannot hide the header image on that specific page. I am desperately looking for any help. The sites url is http://retroshow.hu as you see the front page is messy.
Any help would be really appretiated.
Sorry but kinda newbie here :)
