I’m a big fan of the old postcards too. I found a vintage shop near me that sells them for a dollar. I started collecting trios with hopes to send them to family as per series. Seems kind of fun but doesn’t pay the bills. Now it’s just one of those projects piled on top of the table.

Regarding your question about oranges: my favorite way to consume oranges is in Kombucha! Especially blood oranges. They are they best for Kombucha. I bet you weren’t expecting that. 😁
I have a second answer. When I was a kid (yesterday), I would bite a small hole in its skin and then suck out all the juice and pulp through that same hole. These days... I don’t eat enough of them and I would probably just peel it with a butter knife.
