Evidence of Time Travel in early Mets Yearbook covers!

I am scooping myself here.   I started another Coronavirus Filler series for later in the week, but I noticed something….

1.  Mr. Met, 1963.   Why does his cap have an orange brim?  Is he a time traveler?

2.  Why is the kid wearing an orange lettered fashion jersey in 1965?  Is he a time traveler?

3.  Why does the kid’s cap have an orange squatcho in 1966?  Is he a time traveler?
