I realize the OP probably did not make this poster in the image. However, it contains a grammatical that error grates on my nerves, so for those who care:

Let us *lie* in the sun if it is ourselves we are repositioning. Lay takes an object, like "let us lay the stones in the sun" or even "let us lay ourselves in the sun".

Just call me a grammar curmudgeon and be done with it. 🙂
