Offered for sale is Costigan's poem, "The lightning-Shattered Tree." It appears to be his self-composed obituary. The cover has two diagonal stains from the glue in the envelope is which it was included; a photograph of Costigan that was taped to the inside of the cover has separated and left tape stains; and there are a couple of check marks on the left side of the poem. But a most interesting piece of Colorado memorabilia.
Don't be shy; give it a try. Doc deals!
