The Adventures of Jo, Zette and Jocko: Mr. Pump's Legacy, Destination New York and The Valley of the Cobras by Hergé

As previously noted, much of Hergé's non-Tintin work isn't well known in English because so little is still in print in translated form. However, there is one other series with three albums currently available in the UK, which can often be found alongside The Adventures of Tintin in bookshops.

The Adventures of Jo, Zette and Jocko are the tales of a brother and sister and their pet monkey. Hergé created them on request from one of his French publishers but ultimately only produced five complete albums. Two of the albums, The 'Manitoba' No Reply and The Eruption of Karamako, have only had a limited English-language circulation in a double-volume that used the overall story title The Secret Ray and is now out of print. Some of the depictions in them are controversial and were thus passed over by first Methuen and then by Egmont.
