Fixing some of the outstanding issues produces another Apollo Eagle from layers of punched cards:

Stipulated: nobody ever ran punched cards through a multi-color printing process. A posterized version of the Apollo 11 mission patch eagle just seemed appropriate for cards containing a chunk of the mission source code.
Putting the tail feathers on two layers of reversed cards definitely improved the outcome:

The lines across two of the tail feathers come from inadvertently printing a quilting pattern intended for Letter paper after setting up a stack of 1/3 Letter blanks. Trust me on this: you do not discard any salvageable blooper cards.
The wing feathers get more definition and have sculptured upper layers:

The olive branch improved with fewer layers and contouring the claws makes them less chunky:

The beak and head now have slight contouring, with the neck feathers standing out nicely over the logo below:

Although this is the third almost-ready version, it rests on the wings of many previous attempts:

The card joints on successive layers are now farther apart, although the long run across the middle of the body stands out more than I expected. The small pieces of cards at the top of the wings need more contrast.
