OK these are obviously not mine but I find them intriguing. I have never heard of Camel Express. This seems to be a
"revival of" set of letters from the
Philatelic club of Los Angeles but I'm wondering if the original Camel Express covers adorned such a mark or if anyone knows an more about this? Fascinating the things one finds whilst rummaging through an auction site. Thank you for your time and here is the link.
