Peanuts Snoopy 1958 Kids Roller Skates

Vintage Snoopy kids skates size 12 ?    I see a 12 circled inside but not positive it’s the size. They are about 7” long 2” wide. They look like they could actually be used again but would also look good just sitting on a shelf.They are dirty, I did not clean them up - not sure what to do for preservation. The laces are very bad ,but I’ll leave them with skates.
