Livraria Blu is Linda's second book-selling business, located in Rio de Janeiro. It is a Brazilian version of Blue Macaw Books. On the window are two crossed, blue feathers, which symbolize Blu and Jewel's union.
Trivia[]
"Livraria Blu" means "Blu Bookstore" in Portuguese[1].
The bookstore is only shown during the ending credits of Rio.
It's possible that Linda has either shut down Blue Macaw Books or passed down its ownership to someone else because of the new store in Brazil.
Considering the work Linda does with Tulio (both at the Blu Bird Sanctuary and their trips to the Amazon), it's possible she has someone else run the store.
This is the third place where something is named after Blu in his honor.
