The car in the back is on a rather short wheelbase, it has a very short rear with high placed taillights, the bumpers seem to be ribbed instead of rounded, and the grill seems to have an accent in the middle. Therefore I'd say (and I'm pretty sure) that it's a 1949 Plymouth. Though I'm not sure if it is a DeLuxe or Special DeLuxe
It is not a Plymouth .Grille is Dodge 1949.It is a Dodge Kingsway series D 32 C on Plymouth's 118 1/2 inch wheelbase of 1949 , Plymouth based Dodge ( let's call it export ) model.
