I own several complete sets of this series including double obverse & a Ra, specifically because of the pictographic ideology and as a symbolic gesture of solidarity towards SGB.
The taxation story is scandalous. The SGB protagonist is still about, if you know of whom with which to mingle and ask quietly. These rounds have a cult following, if you own them, HODL.
