I keep looking at this and can’t figure out what Mr. Met is wearing and how he would come to acquire such a cap.

I don’t think it’s a lighting/flash thing

Maybe it’s a vintage cap he has from the 80’s when the blue was a little more of that electric blue? Maybe his cap is just faded from use?

Is Mr. Met getting his stuff on eBay? We will have to keep our eyes on his jersey collection.
Anyway. nice to see Mrs. Met looking sharp.
