Did you read the clues? ( you need to go back to the thread that the post is in, to around March 31, 2014) Click on the thread title: "What did you do today?"
Anyway,
Look at the thumbnail of the article pic. Don't expand the photo, don't study it, don't think about what it is supposed to be. Just glance at it from a ways back and not being able to discern that it is even a tub that is there. What do you see?

viewed at from slightly above.
The tub wall is the hood, the inside of the tub depicts the windshield and the tub rim depicts the car frame surrounding the windshield. The platform makes the rest of the car front on either side of the hood complete with the headlight eyebrows, as those cars had back then.

Actually, I don't think anyone else saw it either, except us in the Lilies forum. Otherwise, I'm sure there would be at least a few posts here, declaring their success with the puzzle.
