The colours are fairly accurate in the catalogue illustration. The work is executed on its original canvas and is not relined. Few wears located near the rim of the upper and left edges, probably due to a re stretching, are only visible under very close inspection. The ocre/brown thicker brushstrokes on the upper right corner presents some hairline stabilized cracks. Under Ultra Violet light inspection, one small dot of retouching fluoresces 41.5 cm from the right edge and 19.5 cm from the upper. This work is in very good condition.
