Bob Dylan singed vynil on ebay from Argentina for USD 200. Is it real?

I have seen 2 different signatures from him, so I don{t know the real thing

I recentrly read that his singature cost USD 1275 (I don{t know if that preice is over a singed vybil, a musicak instrumet or autographed over a single piece of paper)
