Taken on January 25th, 1930, caption reads:
'Who's been climbing up my tree?' said the little sun bear at the London Zoo, and he could scarcely believe his eyes when he saw the big black bear proudly scated on the top. Without more ado, the little sun bear literally ran up the trunk, engaged his big mother in a tussle, and after pulling him down, claimed the position on his very own.
