"No returns" on ebay is more funny than annoying. No returns, huh? Want to bet?
"The pictures are part of the description" is annoying. Just describe the damn item. Your s****y pictures don't show me anything.
But the most annoying as a pennant collector is the application of any baseball card grading classification to a pennant. There's no such thing as a VG or EXMT pennant. Pennants should be described based on their...oh I don't know...exemplary "eye appeal".
