HyperGIS -- Bridging the Digital Divide.
All cards are welcome. So, surprise me. The results have been good so far. I got some excellent cards that I wouldn't have received otherwise.
If you are not sure, it's always good to send me tourist cards showing where you live or where you had visited.
If you still prefer more specific suggestions, I'd love to have cards of:
Maps, aerial photos or satellite images;
Lunar New Year (Year of the Tiger for 2022) and/or with those stamps;
STEM (Science, technology, engineering and mathematics);
Geography, space and astronomy; especially geographic landmarks or monuments such as the Tropic of Cancer, the Arctic and Antarctic Circles and the Equator, survey points;
Earth Day and climate change themes;
Don't worry if you don't have any of above.
If your card has traveled much longer than usual, please contact me.
