Welcome aboard. I flipped the images for you

 

We need the other tag to the right of that one as well.

being left handed I always managed to get the photos sideways.  Todd or a moderator usually flips and expands them.

I'm trying to decode this using Catalog of Canadian Car ID Numbers but immediately run into a problem with the style number. I suspect this is a misprint in the book.

style 2019D = not listed ( they list a Laurentian 4 door as style 2069D )
body 1931 = consecutive production number
paint 2512 = suspect its dover white over sierra gold metallic ( really not sure of this. )
trim 911 = ?

Serial number 72019D621470
7 = year =1957
2019d = see above
6 = 6cylinder 261 cu in
21470 = sequential production number.

list price = $2981
weight 3290 lbs
manufactured Oshawa, ON

I really like the looks of your car. tell us more about it.
Lots of friendly Poncho guys here who are more than willing to help.

You may also be able to get documents on your car from GM Vintage Vehicle Services ( ggogle them ) for a fee. Not sure how detailed the info for 1957 is.
