No official digitization. Heinlein (Omega Design, 1999) is a freebie made by Michael Lee based on in-use samples on Robert A. Heinlein paperback covers, and hence not faithful in all details. Modern Vision (2011) by V. Sarela is another reconstruction based on various in-use samples, and comes closer to the original.
