From last month about the Mark Hamill signed posters helping raise funds for Ukraine:

“$311, 046!!!” - https://twitter.com/MarkHamill/status/1639720548099063808

“The raffle of posters signed by @MarkHamill is over! We have raised over $311,046 towards RQ-35 Heidrun reconnaissance drones for our defenders. We’re grateful to our dear ambassador and everyone who joined in!” - https://twitter.com/U24_gov_ua/status/1639670157176889347

Well done Mark Hamill, and everyone who donated.
