Picasso or Not - Who Knows?

.
Between 1947 and 1973 Picasso reportedly produced and/or decorated approximately 4000 ceramics. Of these one-off pieces some 500 items were reproduced in 'edition' copies by the Madoura Potteries in Vallauris. Those selected were issued in editions ranging from 5 to 500 copies. I have no idea how many copies were reproduced in total although each item was marked as an edition piece together with total number in the series i.e. 126/500 meaning; reproduction 126 in a series of 500.

It's difficult to understand where that figure 4000 came from and to know if anybody has a true record of how many ceramics Picasso actually produced in total.

The helpful and ongoing 'On-line Picasso Project' (link to the right) identifies just 765 ceramic works that they believe were produced by the hands of Pablo Picasso. What has happened to the other 3235 (approximately) ceramic artworks he is reported to have produced? I have yet to consult Zervos and other catalogues on this matter.

Not all his output can easily be accounted for. I believe the plate shown above to be the work of Picasso and am trying to prove it.
