Thomas the Tank Engine (found original illustrated edition of book; 1946)
Thomas the Tank Engine is the 2nd book of The Railway Series published in 1946. However, when it was published in 1946, it had illustrations done by Reginald Payne instead of the ones done by Clarence Reginald Dalby. The 1946 edition was lost but the original illustration example was found by TEngine on TTTE Wikia. The TTTE Wikia now has all of the other illustrations available on their page on Reginald.
