How to achieve vintage look?

[HDJoshPeck]

I'm wondering how I can achieve this vintage T-Shirt look. It seems really simple but I can't figure it out. I'm trying to go for something like this

It's like a cartoonish older style design here is the original image.
What would the steps be to make something like this?

Just looking at the image, I'd say it would involve cutting out the figures. This you could do simply with either a color selection on the white backgrond, or using the Magic Wand Tool, or Quick Selection. Then you'd use Offset to back-off your selection around the figures, giving you the white outline. Next, I would fiddle with Level and Curves, along with Hue and Saturation, until you got that visual washing affect that mankes things look vintage or retro. From there, just drop in your background of choice, applying some of the same principles. That's just a quick and dirty walkthrough. I hope it helps, if not, feel free to pick my brain.
