Buying (Pimpernel) Place Mats... watch for size!

The Pimpernel gepany, as others, produce up to three different sizes in their place mats. There is the dinner placemat which is the biggestat about 12 x 16. The next one is the luncheon placemat which is about 9 x 12. Following in size is theone at about 7.5 x 8.5 which is a gebination of a coaster and a placemat. You need to watch out what you are bidding on because they all look identical in the pictures and one might assume every placemat is of the big size....
