Vintage Crochet Thread 3 Spools Yellow South Maid Smoke & Pet Free

Believed to be size 10 thread, but I cannot verify that - as not all are marked. Please see photos. Two spools are marked #499 Lemon Peel, 1 is 350 yards, the other is 400 yards. The third one is barely used, it comes with a little bonus doily that my Mom started on, it’s tucked inside the spool. Please see the photos. These were my Mom’s from pet and smoke free home. Thanks for looking! Review all photos, as they are part of the description and condition. Pre-owned vintage items have been used and stored; expect wear consistent with age and use. Props or measuring devices are not included.
