Childhood Nostalgia

I don't know what it is with me these past few days... It seems that I'm looking for old memories in everything and finding traces of my own history in different items found in the basement or in the boys' room. These are my first shoes...

I was born in 1974. I remember this holder for the milk cartons. We used it every day and you can see it on photographs from my birthdays, when I was a little girl. Why don't we use these anymore?
