Another consideration if you have the space for “depth stacking” is our offset shadowboxes. In each 12” or more of length, the side gets deeper by either 1/2” or 1” so the building “flat” is technically no longer that against the backdrop surface. This is our Lehigh University color-schemed (brown and white) three piece UP Trackside Warehouse (WH-1). It is 1” deep on the left side and 3” deep on the right side.
