Note: the plate was higher lead than the bowl, and they look like they are from different batches based on the maker’s marks on the bottom. The bowl / saucer was in the neighborhood of 350,000 ppm lead.

For Context: Items intended for children are required by current legislation to be under 90 ppm lead in the glaze, paint or coating. Dishes (especially vintage dishes!) are not regulated for total lead content (as detectable with an XRF instrument.)
I would not ever consider these dishes safe to eat off of. If you have dishes like this (any dishes from Franciscan actually) please consider disposing of them and perhaps just saving one and putting it in a shadow box (behind glass) with a story about how it came to be yours (whatever family story is important to you in relation to why you have the dish.)
As always, please let me know if you have any questions.
