Just sent out my 25 this morning. I've only received Uwe's card so far–the old paper lends itself nicely to the image. Looking forward to the rest!
For those interested: Had some fun trying to figure out the reciprocity failure on the TMax 100–my meter gave an exposure of 4 minutes at f/22, and the 8 minute exposure came out the best. Keeping everything dust-free over the course of making 28 contact prints was challenging, but I think it went alright.
