Russian Dolls

750 pieces, Wentworth.  A recent discussion prompted me to conclude explicitly that, were cost no object, all my standard Wentworths would be 750 pieces--I think it's the ideal size for difficulty and interest.  This puzzle had some nearly-repeating images that made things harder.  And I forgot to take a picture of the final, sadly!  I include a box picture for completeness.  3/5
