Hi, I had a sale on Alamy :
"Country: Worldwide
Usage: Magazines and books
45 MB
4592 x 3448 pixels
2 MB compressed
Start: 25 April 2022
Duration: In perpetuity"
Can you help me understand what start date and perpetuity mean? I did not receive a large amount for this sale... will I receive an amount each year? or is it a one shot deal?
thanks
Chris
