For the ACP i found random, mostly art related pieces around my house such as crayons, a copy of a drawing I did, origami, and a coloring book picture. There were also un-art related things such as a seashell, an LA parking pass and a map.
The similarity of sending someone an ACP and a Snapchat is that it’s a form of communication. Both allow each person to start a conversation and express themselves in the types of pictures or media they send. However, Snapchat is limited to the amount of words you can send at a time and it only portrays a snapshot of that moment that soon disappears. An art care package on the other hand, allows you to send pieces of memorabilia that can be kept for as long as desired. For me, I think ephemera is precious when you can look back on the piece and remember a special memory like a movie ticket from your first date. But if you keep every single ticket for instance, I think it looses its special meaning because you start to forget why that ticket was special. Ephemera given to you by someone else like your grandma I think is only impactful if they tell you about their experience and the story about that ephemera.
