I got really curious, so I looked it to see what numbers are available. I found a list with the top 48 selling Picasso paintings. The most expensive painting was sold for $179.36 million and the cheapest on the list sold for $2 million. The total for the top 48 is 1.422 Billion dollars. I assume none of these are private sales and that could be another factor for consideration.

The total market cap for all cryptocurrency markets is something around 886 billion, so given the asymptotic nature of the sales (13,500 paintings, 300 sculptures, 34,000 illustrations, and 100,000 prints, and maybe some poetry) it might not be the best measure.

For the remaining 147, 752 piece (not including poetry) and assuming each remaining piece is worth $1 million, then the remaining value can be estimated as 147.75 billion. Probably not larger, but still quite large.

The above is a really generous estimate by someone who is terrible at math, so your YMMV.
