Design a rectangular banner ad and logo/favicon

I sell lego. There is a new lego marketplace online to compete with bricklink, where i opened my first store, I have now opened a store in the new site with the same name. This is a more modern site and you can include a little square logo and a rectangular banner type thing with the store name.

This is a store example: http://constructibles.brickowl.com/
This is my store: http://abricktoofar.brickowl.com/
This is the page where all store are so you can see the logos: http://brickowl.com/stores

Can you help me out with ideas? The theme should be that you are missing a lego brick, which is far but can be easily accessed with my help. Maybe a lego 2x4 brick with wings coming towards a lego man??? I don't know... The logo could be same brick with wings??

What do you think? I am looking for some ideas and insiration

Thanks!
