Here are two more of those scary Popeye pics. :)
The first one is from May 23, 1933 taken at the Chicago World's Fair.
The second is from April 26, 1939 and has the following caption on the back: "KFS comic strip characters arrive at KFS performance of Hellzapoppin'"
I dunno, but here are the photos anyway:
And here's a bonus Segar I saw on eBay a while ago. Enjoy!
