Can anybody tell me what the deal is with the drawing? It appears to be a Last Supper-like depiction, but with all girls? It is strange to me - especially because it is a First Holy Communion Remembrance certificate from 1933!

More info: This Remembrance certificate is by the Edward O'Toole Co. in NY which was a successful Catholic goods business. There is now a Theresa & Edward O’Toole Foundation that was apparently started with this company's profits.

UPDATE: This is not a photo as I first wrote, but a drawing.
