826LA has been donated a few 1981 Los Angeles Bicentennial Celebration posters, and are making them available to you in the store and on Ebay.
They have three 2′ x 3′ reproduction posters designed by post-surrealist painter Helen Lundeberg available on Ebay for a starting bid of $19.99 – so far I don’t think anyone has bid. According to their Facebook page, 825LA also has posters available for purchase in their store, the Echo Park Time Travel Mart, which is located at 1714 Sunset Blvd.
826LA is a non-profit organization dedicated to supporting students ages 6 to 18 with their creative and expository writing skills, and to helping teachers inspire their students to write. They offer tutoring for the kids Monday through Thursday from 2:30 pm to 5:30 pm. You can learn more about the program and their volunteer opportunities by visiting the 826LA website.
