So, you think you know comic book grading? We'd like to hear from you!

We're hard at work on this summer's new edition of The Official Overstreet Comic Book Grading Guide. We've had a lot of feedback since the last edition was published more than three years ago, but we're eager for your thoughts.

This week's question:

How would you define "Restoration" in comics?

What would you include and not include?

Would you delineate between professional restoration and amateur restoration? And if so, what would be the determining factors?

What, if any, forms of restoration are acceptable to you?

And why?

And under what circumstances?

We're eager for as many opinions as possible! Let us know what you think!
