Hello,

You can only add a background image with an eventTicket pkpass

Instead of background.png use strip.png or change storeCard to eventTicket.

Refer to http://developer.apple.com/library/ios/#Documentation/UserExperience/Conceptual/PassKit_PG/Chapters/Creating.html

Table 3-1

Hope it help ;)
