The Ghost of Christmas Past is described as a 'strange figure' as it is illustrated as a paradox between a child and an elderly figure. It was 'white' as if with age"however, not a single 'wrinkle' present, metaphorically indicating time rapidly passing for both the Spirit and Scrooge. The paradox can also be seen as the contrast between Scrooge's former self and his present self: much like how the Ghost is seen as both a child and an old aged person, Scrooge must has a trace of his younger, kinder self somewhere within him.
