Vintage Baby items

My baby items I kept all these years These were my little shoes as a baby. 1960s. Inside the shoe it says 50M 3899749. I was trying to see the brand but it's pretty worn off. Ser...not sure what the rest of it says. Asking $10. Handmade crochet or knitted sweater, cap and booties from the 1960s. These were mine also. I don't know if I ever wore them. I asked my mom when I got them, but she couldn't remember. Asking $20. Located in Killam Alberta.
