‘María De Buenos Aires’ it says in black letters on the van. It’s an older model, but well cared for and trust inspiring. All the important parts, such as its shiny wheels and fenders, look new and expensive. White, compact, and sturdy, it has been converted into some kind of multi-purpose mobile home/trailer. The initial passenger space now serves as a tiny stage dressing room or, if needed, as a bedroom. There is a clothes rack with stage costumes, a vanity, and everything the artist needs to transform herself for a grand appearance. This past year there were thirty-three of them in five months.
