Stan Drake - Eve Jones from The Heart of Juliet Jones

The question is, would you be ever be able to identify which strip this came from?  Pretty cool though and unique gift.  Most artists wouldn't have bothered with the extra work here and sent a whole strip.

I agree, as fan I sure would have preferred an entire strip to just part of a panel! I can't devine the thoughts going through Paul's mind when he received it, but I would have been absolutely excited to receive a reply with a drawing from Stan Drake, followed by being ever so slightly bewildered, and definitely fascinated by the fact it was part of a strip. 
I'm not sure how robust of an original art market was in the 60s, but perhaps Stan thought of the value of the original art as contributing to the production process and not having as much value on its own and as such, felt comfortable cutting up original strips to serve other purposes?

Well, Drake cut up a great one.  I mean, maybe he didn't even have to cut up a particular strip to send something to a fan.  I have a few JJ strips where Drake had cut up parts of previous strips for new JJ strips.  A real shame.

Thanks for the insight. The process and output to create a daily strip is a fascinating process! Now, artists can digitally cut and paste images, in the 60s, one used a steady hand, scissors and glue!
