I am, apparently, on a penguin kick. Here is another card featuring a penguin:
The card base is from SVG Cutting Files. It is called Curved Card Base. It is about 5 1/4"x6 7/8" when folded.
Both the airplane and penguin are svgs from Kadoodle Bug Designs. They were in a set called Air Force Penguin, but it has retired, and is no longer available. The airplane is a little shorter than 6" wide. The penguin is 3 5/8" tall. I pieced them all together, then used a white gel pen to add a little detail. I also used acetate to cut the inner part of his aviator goggles. The penguin is mounted to the card with foam tape.
