Glowing softly in the West Texas desert night, artist Guadalupe Maravilla’s Mariposa Relámpago, was once an ordinary school bus but is now a richly decorated, mobile site for remembrance and healing. Like much of the artist’s work, this piece commemorates and confronts the artist’s journey to the United States as an unaccompanied, undocumented minor fleeing civil war in El Salvador in the 1980s.
