Tarzan - 'The Duel', page 3 (1967). TV Tornado #26.

Last page (comic page 9) of a three page Tarzan story called 'The Duel'  published in the UK comic 'TV Tornado' #26 in 1967. 

Ink on paper - approx 18 x 14 inches.

The artist is probably Harry Bishop, but I stand to be corrected. 

Tarzan looks a little like Johny Weissmuller in the last panel. 

The artwork was too big for my A3 scanner so I had to scan it in two halves and join the images digitally. Hence there is some slight misalignment in the image shown about half of the way down.
