The second tree indeed has its interesting story. This is one of the very first Casuarina bonsai in Indonesia. I used to belong to the late Mr. Ismail Saleh, Father of Indonesian bonsai, the Founder of ASPAC; it was first displayed in the 1st ASPAC in Bali in 1991 and won the award from Saburo Kato.
Then, about 8 years ago, I found it dying at the corner of Mr. Saleh's garden, most part of the trunk was rooten; then I adobted it to be secured..got it restyled...
