This is a very nice double specimen of Elrathia kingi from the Wheeler Formation of Utah. Both trilobites are complete and exhibit fine detail. They are totally natural to the plate - they have not been composited. Both trilobites still have both free cheeks intact, which is quite unusual. The black trilobites contrast beautifully with the grey matrix. The bugs are well positioned on the natural plate of shale. This is a very fine double specimen of this classic US trilobite.
