Vintage Camera and Photos

Maybe this would be better somewhere else but since its not really a canon specific question I placed it here.

Anyways, my question is:
What would be the best camera to buy for photos that look like they were taken in the 20s or 30s?
(I have Holga and thats as old as I can get at the moment)
Are there any old cameras that combined with film can produce some nice vintage pictures?

Images from the 20s and 30s look like they're from the 20s and 30s because of the era (clothing, transportation, architecture, etc) and the degradation of the film/print over time. The Holga helps speed up the process by letting light leak into the camera, thereby damaging the film immediately.

And probably the printing as well.
But Ive seen some really really old glass give some great soft vintage effects.
So the camera/lens must help a bit?

If you just want soft, you can get an old POS lens that's yellowed and fungus-filled. Some people are good at photoshopping the vintage/antique look but I'm not one of them.
