The "Disney Girls - Reveal/Conceal Mystery Collection" series of pins consist of a run of designs that are all related by either characters of the same movie or through the design itself. Also included in the Reveal/Conceal series is a "chaser" which is a rarer concealed pin. Traditionally a Reveal/Conceal series will have a long shelf life and are typically a limited release, which means the series is limited edition, although the edition size is not publicly shared. The "Disney Girls Reveal Conceal" series was released on Dec. 12, 2010 and sold out within hours. This series eloquently depicts some of the most famous Disney Princesses, framed by a gorgeous filigree frame of complimenting colors. In this line of Disney Girls there are three levels to consider and all are identifiable by the detail in the design. On tier one the pin does not have glitter fill or jewels. The second tier has glitter along w/a single jewel located in the bottom center. The "chaser" or rarest of the run is noted by the inclusion of three jewels that are placed along the lower portion on the Rapunzel pin. Offered here is PinPics #81320, a 1-5/8x1.75" enameled metal pin graded and encapsulated by PinPics depicting Ariel from Disney's 1989 animated film "The Little Mermaid." This is second tier w/small red rhinestone accent just below her portrait and glitter fill accents along bottom margin and to small castle in bkg. PinPics graded at 9.3 (NM), none graded higher. From one of the most attractive series of Disney pins ever made, the Reveal/Conceal Girls limited release was released in 2010 from the Disneyland Resort. Edition size is unknown but conservative estimates are between 200-300. Only the ultra rare Rapunzel chaser (see item #2133) from this series has proven to be more elusive.
