What we know so far:
• “We always heard that the missing Cassatt mural was at Notre Dame University, in a tunnel underneath campus that extends from the current Art and Art History building.”
• Three connections to the world of Chicago art:
Otto Lightner bought up a lot of art during Depression with a kind of take-what-you-want, but leave the rest approach among his Chicago neighbors. He moved his collection to St. Augustine into the old Alcazar Hotel of Flagler's empire sometime in the 40's or 50's then promptly died. It sat for more than 20 years.
Less exploitive was the collection of Frederic Clay Bartlett and his wife Evelyn Fortune Hunt. They certainly had the eye for great works as seen by what they left CAI.
Both sites have storage areas that a[re] less than academically inventoried.
There is a great deal at the Ringling Museum in Sarasota, but their catalog is available. . .still?
