These sure are some gorgeous um.....speakers! Scroll down a ways in each listing for a nice large photo of each one. Whoever was in marketing at Altec in 1976 was a genius! I wonder if there was an Altec "casting couch" where these models had to "audition" to get these jobs.... So far bidding/price seems reasonable considering these are rare originals. No affiliation yada yada.....
