I usually take some pre-delivery photos to double check the set-up and also helps as many times the venue is not completely set up or does not have good lighting. Here's the tower minus an extra cake tier which I will stack at the venue.
The cupcakes were strawberry vanilla and chocolate sour cream. By the way, if you don't recognize the sugarpaste "records" then you are young! :-)
Here is the final set-up with the additional tier. I forgot to take photos from the other angles, but the cubes also had the guitar and record design on the other sides.
