Well, I should have anticipated that, but the first people to contribute logos to the pageant of trademarks slide show, sent in logos for their own trademark firms. But, given that both logos had artistic merit, they have been included.
You can add to the show by emailing a JPG or a PNG (no other format) file to TRADEMARKS at CELLBLOCK dot Com. No subject heading is necessary. I monitor all submissions.
Remember, the button bar at the bottom of the Cellblock viewer allows you to go forward and backward, change the speed, and allow for full screen viewing (turning it into a nifty screen saver).
