@dmeyers look at the beginning of the thread, I explained it there.
I can add that the last sig. picture you posted is much more crisp and one can appreciate the brushwork of this master. He is skilled in both disciplines (calligraphy and ink-painting) and dead as well (sadly), so his works might be quite pricey. Also, he is listed in the Japanese artists DB. I gave a link to his name few posts back.
