Mr. Mind Strikes Again!

Those of you who haven't given me up for dead may recall this posting on my birthday back in April, where I drew Captain Marvel's famous arch-enemy, Mr. Mind, following instructions in an old SHAZAM! issue.

Comparing the two now suggests to me that the other one may have been done a year or so later than I previously believed, though it's possible that I may have just put more effort into the other one.
Actually, further investigation confuses the issue even further. I've just determined (between the two paragraphs) that this drawing is unquestionably from late summer/early fall 1977. So it's definitely the same age or newer, just more hastily drawn. So that's that.
