Angler's Canvases

I'm sure in the thousands of posts this has been asked before, but is there any possible way for guests to see which fishes are on your Angler's Canvases? Some of the fish are rather difficult to catch, and it'd be neat for guests to your house to be able to see what fishes are printed!

Nope.

You can leave the names in your message book, or just tell them directly, but there is no way for them to determine it themselves without pre existing knowledge.
