I have received permission from the list manager Mr. Roberts to post on a one-time basis the following item that folks on this list may be interested in for their Twain collection. Please e-mail me directly if you want details. For sale: Several airmail envelopes printed to celebrate Twain's connection to Halley's Comet. (His birthyear coincided with the 1835 appearance of the comet) These were produced in 1985--another appearance of the comet--and are in excellent condition. They have color pictures of Twain and the Comet. I'm only asking $10 for five of them. E-mail me at [log in to unmask] Thanks!
