Wasting time online this afternoon. Found this listed in google answers, someone asked about the very first credit "cards." https://answers.google.com/answers/main?cmd=threadview&id=63353 Was an interesting (and comprehensive) answer to the question, made me think of this board. Interesting reading if you have a minute or two (or just want to avoid working, like me).
excellent work avoidance moment. you learn something new everyday, and I usually try to forget something old.
