literally bottles

Yesterday, I mentioned the postcard that depicted the office of the Diamond Bottling Company, which was located down the hill from my old home in the Hopeville section of Waterbury, CT. I wrote that "the postcard says that the building depicted on the postcard was 'built of ginger ale bottles.' I wonder if that statement is literal or figurative?"

The card arrived in the mail today and the answer is literal. On close examination, it is clear that the office was actually built using ginger ale bottles, as can be seen in the accompanying picture zoomed in on a corner of the office building.
