A quick way (if you know a little bit about photoshop or lightroom, or a similar program) to get a picture like this is to google "vintage post processing actions" (for photoshop) or "vintage presets" (for lightroom).
A lot of people are really good at post processing, and they put up free actions or presets. You can download them and apply them to your own photos.
You can also look at the steps these actions went through to achieve the final result, and you can learn that way.

(I just googled it, I haven't used any of them myself)
