I recently received a beautiful Gotochi card from a 14 year old Postcrosser in China. Sadly there was no Username, no Postcard ID and no return address. I reached out to the moderators but there was not enough info for them to figure it out.
A not that helpful but rather entertaining point: the bottom line reads ‘8th March Square - 1’, whose namesake is apparently the international women’s day; very socialist, isn’t it?
By the way, the cartoon stamp might be a clue as well. You may search the meet-ups that were held in Dalian City and find the organizer to ask if by any chance they know the owner of that cartoon stamp. Because most participants of China’s Postcrossing meet-ups have their own unique rubber stamp.
Thanks for your efforts! I have managed to locate the Postcrosser who sent it and send thanks. So I appreciate your efforts! But no further efforts are needed.
