Part of the 400+ series.  Three like drawings derived from a single image of one person laying on another- both resting above a pool floaty.  With these the drawings shifted to a bit darker as I started using more india ink.  I wish i had some white ink- i need to get some of that so I can re-work the dark areas.  Sometimes white pencils work, sometimes they don’t.  I like white and blue for reflecting light and ripples, but sometimes those waxy materials don’t work well over certain washes or non-jet back washes.
