As requested, here are some places to look. Golden age comics are the best for this sort of silly stuff and many are public domain, so there are multiple places to look for them. Be warned, it is overwhelming. They churned out comics back then like they were gum wrappers.
If anyone has other resources, feel free to add them. Please no pirate sites, there's a lot of "read today's comics online for free" sites which would violate lemmy.world ToS.
Should/can we post context in the posts? It's hard with copyrighted comics, because you can only really link directly to pirate websites. The best you can do otherwise is say like "Superman (1939) #7, page 25".
I would avoid links to pirated content since it violates lemmy.world ToS, but feel free to link to any PD comics. I think otherwise, yeah, you'll just have to say the comic and issue number.
I would prefer adding context in a spoilers tag, if you're going to do it. Especially if you're going to describe the situation. And also what Squid recommended.
Spoilers tag just lets everyone else maintain ignorance for the lols.
Another good idea is to get an image compression app. I tried a couple online sites, Sqoosh and Image Resizer, but those were having trouble on mobile for me.
So I ended up just DLing an image compression app from the play store, and it works great. The one I got was "Photo Compressor". It has ads, but you can do multiple pictures at once to limit the ads.
Not sure if it's on the play store or not, but you can download the apk directly from that page if it's not and you don't already have F-Droid installed
Tried looking at Secrets of Love and Marriage and some other similar ones on digitalcomicmuseum.com. Mostly a bust, the genre tends to be really wordy and also just bad. I did find this, but context actually makes it worse. It looks normal, but the context is that they're pretty much step siblings:
