As I daily scan new topics on the Forum, O Scale decal availability, is occasionally listed as a topic. I did a general search for DT&I O Scale decals and the Tichy Train Group of Alamance,NC. was highlighted as a source on the web. Upon going to their web page I downloaded their decal catalog, they have a good selection of decals and pricing is reasonable. Decals are water slide and they also do custom decal printing.
