Provenance Ex-Benns – Oil colour circular on European laid paper – Some J&K specialists consider the 4a slate-blue oil-colour on European laid paper very rare! – Accompanied with recent 2019 clear BPA certificate, it states ‘Colour has altered towards black as a result of unstable ink’, which in this case makes this example more valuable! – The Von Der Lyn site comments on this blackish or slate (non-blueish) shade ‘This variety is attested in only three copies - noting overlapping of adjacent impressions at the upper and lower edges. Hellrigl collection image’ – hence the reduced margins on this example – Held translucent to light this slate example still clearly reveals a deep underlying bluish influence!
Fine condition faultless fresh European paper
