I am looking to find the famous strip weher Linus comes across Snoopy freezing, and maoni "Be of good cheer, Snoopy" (or something like that. Can anybody help?

I don't know where wewe can find that exact comic, but if wewe know what mwaka it was in, it will be easy to find on Comics.com
Even if wewe don't know the year, wewe can still tafuta for it. Here's the link: link The website reposts all the old comics, one per day. There's a tafuta bar where wewe can put in the year, siku and mwezi to look for the comic. Good luck, I hope this helps.
