there are illustrations for some of the products on this site but not all.  the illustrations really help a lot.  (it may not be clear just how important they are to someone familiar with the subject matter.  to a newcomer they are very important.)  also, it would be helpful to have at least one photo and at least one drawing of each item.  in the short term illustrations of poor quality would be better than none (as long as remember to replace them with better ones as soon as you can).   also, an illustration or link to illustration to german product on display in smithsonian would be helpful.  -ef
