Doctor Who and the Roaring Twenties? Two things together that I love - awesome!
Rose and the Doctor really do look like themselves and the clothes are truly life-like and period accurate. (Except for the Doctor's shoes, but then again I'm very glad they made it through the period change unaltered -- and that the Doc is still wearing pin stripes )
Back in high school for my graphic arts class we had to make posters for our school's musical production of "Thoroughly Modern Millie" it was a fun project, but I wished we moved on (we spent two months making posters! When I really wanted to do other projects. I think I should have done graphic arts my senior year...they got tablets that year and Adobe Illustrator). Anyways, I remember using a pattern similiar to one found in a Sears book for my poster of a Roaring Twenties gal.
