That note looks pretty informal. I should imagine formal correspondence is done through a flunky.
I left off a cite. The particular quote is from the tract “Ivan the Terrible” – appropriately dated 1984. You can find it at a site that is half-critical/half-fan:
{Go to the Main (Tracts) Page and then scroll down to “Ivan.” The result does not send you to the online tract at Chick’s site, because it is no longer in print, therefore not on the site. But Kurt has a paper copy displayed here. May be a bit harder to read. It’s no doubt legal because of the ongoing cooperation between the two parties.}
(The more scathing reviews are among the guest reviews, but the host, a fan of JTC artwork and a believer in many of the same things does not hesitate to criticize when he disagrees.)
Also, there is a similar comment in the 1988 “The Prophet” full-size comic.
Look for the “fruitcake” missionary two frame-levels above last frame-level of the four-page display option linked to here.

I just remembered another example.
While I was in the Navy a common form of hazing was the Fool’s Errand. (I can’t call it a Snipe Hunt, because, well, I was a snipe, and that wouldn’t take very long at all…) Generally people could use these as an opportunity to earn respect by dealing with them with style or panache.
But those were rare.
More often we just enjoyed watching a NUB flail about trying to find something that was usually a contradiction in terms. As the wikipedia article I linked mentioned, common items included a bucket of steam, a mechanical punch, or batteries for the sound-powered phones.*
And, the ubiquitous cans of dehy water.
One of the guys I was bunking with when I first arrived aboard my ship was a cook, and he was far from being the sharpest blade in the drawer. He came into the berthing compartment complaining that he’d been trying to find the cans of dehy water all day, and couldn’t get to them.
Several of us in the compartment tried to explain to him that dehydrated water was a spectucularly useless item to make, and that he was being sent on a bootless quest.
And then he proceeded to argue with us that he’d seen such items before, and he knew there had to be some aboard ship - where else would we get our water from?
*Actually, we did have one circuit of sound-powered phones that was used for helo operations. It had an electrical amplifier hooked into the circuit. With a battery back-up. So, I can actually say I’ve seen someone replacing the batteries on the sound-powered phones. 
I remember one of my aunts telling her 7 year old son with complete sincerity that the reason the terrorists bombed the World Trade Center is because they are jealous of America.
I also would like to say that I learned formal cursive in school, but what I use now looks a lot more like the Queen’s chicken scratch upthread. It’s faster and you don’t have to deal with all those weird looking letters.
A Boy Scout summer camp I went to actually sold those at the trading post. 
I got sent to look for a long weight, once. (“On the shelf, next to the jar of prop wash.”) Now, I knew it was a wild goose chase, but I couldn’t think of a suitably stylish, panache-filled reply.
Simple, I usually just said, after having a nice bit of rack time, that the Supply clerk said it was locked up, and couldn’t be issued until their NUB found the keys to the sea chest.
