When I was a small kid, I remember having a typically small-kid-like top with a picture of a dog as an aviator on it. Also, the writing "Dog Gone Flying". The dog had a cheerful, friendly face, he didn't look evil or anything. However, there was something a bit disturbing about him. His face was quite small, compacted down in the lower part of his head. That's not disturbing, it an be quite appealing. What was distrurbing was the fact that, up on his high forehead were a pair of goggles... over another pair of eyes!
In the absence of any photos of this garment, here's a rough impression of it on MSPaint based on memory.
