I searched for one of the registrants in the list, one with a more recent cultivar, Tomorrow's Tulips B.V. and came up with the same site I linked to with the groups, The Tulip Gallery! I don't know if you have noticed Janice, I didn't take a lot of notice but have seen the site before. For each group there's several pages of photos! Could be useful! Clicking on each photo gives more info, year of registration, colour etc.!
