I wonder how much an RCA color TV advertising sign using RCA's old (round) logo would sell for.
BTW, I think the prices on later RCA signs (like the one being discussed here) are far too high. I can't imagine paying anywhere near $1K for one, even one with RCA's original logo. Even advertising for RCA's owned and operated radio and TV stations in New York (when they were known as WRCA) is not, IMHO, worth that much; however, an ad sign for NBC's WEAF (now WFAN and no longer operated by NBC) would probably go for a very high price indeed, since that station goes back to NBC's early days. The same goes for NBC's operated TV station in New York, WNBT (now WNBC); in fact, an ad sign for WNBT when the station was on (now defunct) channel 1 would probably go for a king's ransom, if not higher.
