Largest are the pair about 17 1/2 x 10 each; smallest is about 10" diameter.  All in excellent condition, no defects noted, except one of the pair has a tiny hole near the center and the round one has a very faint pea-sized mark near the edge.  Nice!   I am happy to combine auctions to save shipping costs.  Paypal preferred.  Refund with insured return within 7 days.
