As usual, Analog always shines when it comes to cover art. They've got the fantastic Kelly Freas who supplied rich and colorful depictions for many years. On top of that, the actual printing itself is of decent quality. If you compare this to the issue from the last article, you'll see that having your print lined up perfectly wasn't always the case for magazines like this.
I noticed that the pants on the illustration are tailored with a bit of detail around the tail. There's a snap and a zipper. I can't help but wonder if this was outlined explicitly in the story or if Freas, while illustrating, stopped to ponder how a pair of pants for a creature with a tail would work.
For the issues from my collection that happen to fall in the 60's through mid 70's, I really enjoy seeing what was actually going in the space program during the same period. For example, this issue was published in March of 1969. Readers would be enjoying this issue while also hearing about the Apolo 9 mission on the radio and TV. This was a period of firsts. Many of the flights were presenting large tasks, being done for the first time in space. Apallo 9 was the first space docking, which included transferring people between the modules. That's pretty wild. I can only imagine the wonder and excitement in the minds of the Sci-Fi community during this time.
Publication: Analog, Science Fiction Science Fact
Issue: March 1969, volume: LXXXII No. 1
Cover art: Kelly Freas
Note the tail clasp is in this illustration as well.
Kelly Freas is famous in the world of illustration, and for good reason. Extremely talented, you'll find examples all over of a flexibility in style as well. Look at this illustration and compare it to the ones from the cover or other stories.
It looks like I goofed this scan. I didn't (scanned it twice to make sure I got as much as possible!). This illustration goes into the binding, making it nearly impossible to get fully exposed without cracking the spine. It actually cuts off though, so that wouldn't yield a better picture anyway.
