Lot of five checks signed by Apollo 1 astronaut Gus Grissom, each signed ''Virgil I. Grissom'' and completed in his hand. Checks range in date from 31 October 1959 to 20 May 1965, with Grissom's name appearing at top left. One appears to be a tax payment, addressed to the Treasurer of the United States. Each measures approximately 6.25'' x 2.75''. Bank cancellation marks to a few, with condition ranging from very good to near fine. With a Grissom family LOA for the collection.
