Last year there was a special edition of the "EOS"-magasine about the site of Bernisart in Belgium where 32 complete Iguanodon skeletons were found in 1878 along with crocodile, turtle and fish fossils.
That specific magazine contained a poster of 2 drawings of that discovery one side with an Iggy skull and the other side with a crocodile fossil.
I finaly took time to buy 2 frames to put those posters in
