Old hand carved leather table and chairs

I have had these items for about 20 years and love them. I'm just not sure what they are. I cannot locate anyone or any information on this set.

The hand carved leather, fold-able, table top are the photos I have attached. The table legs are wooden and they also are made to be removed easily. The legs also have small castor type wheels attached.
All four chairs are also carved leather. Each chair is uniquely carved with symbols like the table (none of the carvings are alike). They also fold up into a arch shape.
The actual carvings look like some kind of Aztec type carvings. We were told it was a Ernest Hemingway Safari set.

If anyone can educate me on what I have I would greatly appreciate it.
