Hey, I found this really awesome Etsy listing at http://www.etsy.com/listing/150074279/1920s-gentlemens-hairstyle-guide-11x115
Men's Hairstyles of the 1930's - notice the main trait is lots of gel, very smooth on top. Hair is typically parted very straight and precisely then brushed a little backward and gelled down. Another option is to give it a soft wave in the front - this would be more popular for younger men (Tony). Ed would have more free, unkempt hair with no part.
