Hi Carol! It's always nice to see other U2 collectors here at AML!
Unfortunally Rich is right (he's very good at U2 graphs), these are fake!
If you want to learn more, you can always join the East Link U2 group on FB, or if you're like me and don't use FB here's a link to their old web page with many authentic graphs from early 80s to 2011: http://www.u2eastlink.com/collector/firmas/
