One thing I’ve noticed is the accuracy and specificity of things in his work. The airliner in the first is a Lockheed L-1011. The locomotive is either a GE or an EMD hood unit The airliner I. The second is a Douglas DC-10. And, of course, T-Rex in a F-14.

He mentioned in the 3 volume collection that things are more fun when they’re specific. Like Calvin’s dad is a patent attorney instead of just having a generic office job. As an airplane nerd, it’s cool to see the era of 3-engine planes represented.
