for a spectacular match demonstrating they are pleased with their performance, showing the match is worth their money and worth more than what they paid to witness such an event. This act of honoring the luchador is uncommon: months can pass without it happening, because fans are the toughest of critics, booing the luchador if they are not pleased with their performance. Booing may happen regardless of the perceived virtuousness of the luchador's persona. The luchador, after receiving such an act of honor, will pick up the money and save it as a symbolic trophy, putting it in a vase or a box, labeled with the date, to be treasured. Female professional wrestlers Female wrestlers or luchadoras also compete in Mexican lucha libre. The CMLL World Women's Championship is the top title for CMLL's women's division, while the AAA Reina de Reinas Championship is a championship defended in an annual tournament by female wrestlers in AAA. AAA also recognizes a World Mixed Tag Team Championship, contested by tag teams composed of a luchador and luchadora respectively. In 2000, the all-female promotion company Lucha Libre Femenil (LLF) was founded. Mini-Estrellas Lucha Libre has a division called the "Mini-Estrella" or "Minis" division, which unlike North American midget wrestling, is not just for dwarfs but also for luchadores that are short. The maximum allowable height to participate in the Mini division was originally 5 feet, but in recent years wrestlers such as Pequeño Olímpico have worked the Minis division despite being tall. The Minis division was first popularized in the 1970s with wrestlers like Pequeño Luke and Arturito (a wrestler with an R2-D2 gimmick) becoming noticed for their high flying abilities. In the late 1980s/early 1990s CMLL created the first actual "Minis" division, the brainchild of then-CMLL booker Antonio Peña. CMLL created the CMLL World Mini-Estrella Championship in 1992, making it the oldest Minis championship still in existence today. Minis are often patterned after "regular-sized" wrestlers and are sometimes called "mascotas" ("mascots") if they team with the regular-sized version. Luchadores in the United States In 1994, AAA promoted the When Worlds Collide pay-per-view in conjunction with the U.S. promotion company World Championship Wrestling (WCW). When Worlds Collide introduced U.S. audiences to many of the top luchadores in Mexico at the time. In recent years, several luchadores have found success in the United States. Notable luchadores who achieved success in the U.S. are Eddie
