Our experience has been positive in terms of visitors reaction. Useage is about what we expected -- we will net about $7000 a year based on 50% share. We would do better if the machine was more reliable. Expect it to break a lot the first month -- they seem to need some break-in time. We have a fairly clear contract with the vendor and would insist on a written deal that gives you the option to move it and pull it out if you want. We have an image which is an icon outside our building, and our name. We have a new major exhibit coming this summer and hope to use an image from that in the machine. The judgment about appropriateness is one which every museum needs to consider for itself. Any souvenier item runs the risk of being "too carny". We discussed the machine among staff and review the machine design and penny design before making the commitment. We came down on the side of kids like them, it makes money, and it is fairly non-offensive to most people. You may come to a different conclusion. Now how about photo sticker machines?
