Charles Bukowski - American author

Scored this for $210 with free shipping. Did I get screwed up the ole chocolate wizz way? I checked the signature against the 1980 poetry database here (and my signed 1987 New Years Greeting), and it's clearly a good sig, but the red number is a bit strange.

Is this a Barbra(sic) Martin number, or is 1981 a different cow?

Yes, a ding in the lower right corner, but a good deal in my mind. Or, am I a dumb-fuck?
