Hello Alexandra and... God Rat(lol)
Well, i tried to search for the ballerina on Google like you both had adviced but (if i went to the right post) i do not think it is her! unfortunatly...
It has been very difficult to trace! I do not know what to in order to find some information about Rita Ferreira!
But maybe someday I will find the ballerina, i just have to keep trying I guess...
Thanks for your concern
El
