They aren't in stock at FAO Schwarz yet, but they should be soon any day. Edition size isn't listed for the blonde, but my guess is that both dolls are limited editions of 500, since that is what is listed under the brunette doll. Both are reasonably priced at $50.
The blonde ballerina is the Dew Drop Fairy Ballerina, and the brunette is the Rose Petal Fairy Ballerina. They feature the standard Tiny Kitty sculpt, with straight arms and rare en pointe feet and bending knees. This doll would be a perfect gift for a beginning collector, or budding ballerina.
