It was an illustrated children’s book that I read around 1994 or 1995 that followed a little girl who traveled the world taking photos and sending postcards. She went to lots of interesting destinations. The style of the illustration was kind of similar to Adele and Simon but I’m pretty sure the setting was more contemporary than the 19th century (she had a portable camera). I remember a few pages of illustration that looked like a bunch of different travel images (possibly the postcards or her photographs) stacked over each other in an illustrated pile.
I’m not sure this is right, but could it be “Letters from Felix”?

It’s the toy that travels the world not the little girl – but he sends cards back to her. My sister had this book in the 90s and the illustrations look roughly similar in style.
