Contemporary art glass marble signature ID

[Paul morrissey]

Need help id'ing a signature (and date) on this mib. Tried  Google AI image 3  times and  got 3 different for sure ID's. the usual, so hoping someone out there might recognize and be able to tell for sure, it IS Very hard  to get a clear image so..... But I figure can't hurt to try, Right? I will post a few shots of the marble for reference plus a couple attempts at macro's. It is 1 1/4" diameter with a single pontil which is of course helping to obscure the markings. Thanks! PM

Give this a try…

Take a black sharpie marker and black out the signature area.

Let it dry.

Rub the glass surface with your thumb-pad to remove the marker on the smooth surface.

The remaining black in the grooves will help the signature stand out.

Repost a picture with the black signature.

First guess = Sonny Miller

Best of luck!

Here are some pic's I tried using  graphite, definitely more detail/contrast but still not quite legible to me. Maybe someone  more familiar with these type  of mibs and artist's will recognize it and solve the puzzle? Thanks, PM
