Vintage Felt and Knit Baby or Toddler Shoes with Yellow with Embroidery

Very cute pair of vintage felt and knit baby slippers, not sure of their age but I got them in a lot with loads of other 40s-60s kids clothing so they probably date from around that time. They don't look like they have been worn and one of the slippers still has the a sticker of the foot with the sizing and it says 13/11. They have no other labels or branding.

Please let me know if you have any questions!
