How to use the first appearances database

Search by character or comic title, then narrow the results by publisher or comic era. Each result identifies the debut issue and year, with a short note explaining the appearance. First appearances can be important to collectors, but an issue's value also depends on printing, variant, completeness and condition.

For more help identifying a book, read the comic barcode guide. If you have an issue to sell, send clear photographs through the free valuation form for a market-based assessment.
