PARIS (AP) — Paris' Picasso museum is reopening for two days this weekend after being closed for five years of renovation and expansion that have been fraught with setbacks and dismissals. When it officially opens, 400 works from the prolific founder of Cubism will be on display. [...] this weekend's visitors will mostly be viewing bare white walls, white ceilings, decorative white stucco reliefs, white staircases, and empty display cabinets. Organizers said it is important symbolically for the museum to open on national heritage day, even if the space is not yet ready, adding that the official opening in October will feature actual Picassos on the walls. For Picasso-lovers interested in more than sparkling interiors this weekend, there will be six large-format works made by the Spanish-born artist peppered around the 3,700 square meter space — including the impressive canvass "Three Women at the Fountain" from 1921.
