In March 2015, invitations were sent out to members of Beth El for a gala celebration of Rabbi Rudolph's retirement, to be held May 15, 2015.
The inside of the invitation featured a photo of mine taken in September 2014 at the rededication of the Beth El Sanctuary. (Other photos from the event, including an alternate shot of the one shown below, were published here.)
The photo on the invitation shows a cross-hatching such that it was either edited with a silkscreen effect, or it was enlarged from a too-low resolution version of the original 20MP image, or it was printed oddly.
