			RTTY.COM's Teletype Repairmen and other Data Professionals have almost always carried Credit Card and Ruler-style pocket and wallet references of the various data interchange codes, print element character position charts, and other information of value in their work. They were often promotional items, trade-show giveaways, and "Badges Of Honor" from tech schools and training courses. Here we present a few samples for your perusal and enjoyment. If you have one that should be in this area of "Honor", please send us a .gif or .jpg, and it will be given celebrity status.
