I have discovered a publishing house that deals in adventure travel books, including reprints of many books from the 1930's and onward. Some of these are incredibly similar to the adventures of Indy. I have been reading a contemporary book called Lost Cities of North and Central America, but there is one from the early 1930's called Men and Gods in Mongolia that sounds very similar to IJ & the Dinosaur Eggs. The link to their wesite is below.
