Nice looking fossil shrimps from the cretaceous rocks of Lebanon. There has been no restoration or painting in missing body parts (which seems to be a common practice now!). These are natural with only a light coat of varnish to protect them and they do look better that way but not enhanced with ink or pencil!!! The blue parts of the shrimp are caused by mineral deposits and not ink, similar to those you see on dendrite ferns, caused by Manganese oxide.
Very hard to Photograph - these pieces look much much better in real life!
