Note: This listing of Langsdorf Alligator-bordered cards was taken from an old photocopy of the list in my possession compiled by an unknown party some years ago. Therefore, I cannot confirm that the front titles listed here are verbatim. I would like to thank the unknown compiler for their hard work. For those unfamiliar with this series its primary characteristic is the three embossed alligators surrounding the image. As of Summer 2000 prices for these cards generally range from $30 to $150.
