I have half a dozen possible predecessors, and this one is clearly much less ugly than any of them! The still-life below is very similar (and, more important, stable).

Maybe this could be used instead?Extrementhusiast wrote:Possible predecessor for the remaining still life:The upper left part is in the R-loaf, while the lower part needs to be solved.Code: Select all
