From the picture you posted, they certainly aren't exact matches, but the lip reminds me of Lc. Stephen Oliver Fouraker, an older cross that Hausermann's Orchids in Chicago has. The lip on 'Fouraker' seems to have a little more pink to the color, but it is similar and also has that great ruffled edging in white, with pretty heavily ruffled petals, also.
Here is link to a page that has a couple of photos of Fouraker (scroll down the page some) for your enjoyment!
