I found these in this catalogue which I think you are remembering retronio.
Here is the first picture
Then this one shows the carpets in more detail.
In the grandfather's room I believe the carpet is also different and the photo in the frame is not the one we all know.
Carpet difference in the piano set?
Then there's the vegetables in the basket and the pretzel guy has tweezers.
The homeless man has a different coloured hat and is that a slightly different outfit?
Vegetables in the kitchen and the pans look more 'coppery'
Then the one I'm surprised I've never noticed-the car has brown interior, the top lights are not gold and the girl has a different hat which can also be seen on the next picture. Also are the wheels slighly different or is it just the angle?
