Looking for a specific picture

Hello, I am looking for a specific picture comparing cups I thought (I could be wrong) I found through this forum a few years ago. It was a picture showing many different cups placed on a flat surface with the stems pointing up with lines in the background showing the length of the cups/stems. Those lines in the background had measurements on I believe mm. I think I saved it but not sure where. Anyone?
