there sure is!
i think there were several weinermobiles in the 70s. one came through my small town once. was a big deal.
interesting there was a train derailment the same day as the scalise shooting. no one ever talks about that day but there were congressional repubs on that train. don't know the full story of what happened in your pic but as i pointed out, it was 5 days before ike was sworn in and '53 was a pivotal year. the cia had already cooked up the plan with the UK for the Iranian coup to remove the old Shah. took place in August of '53 under Ike but was not a plan he cooked up though his VP probably knew about it before him.
lots of creepy stuff about that day in dallas. i've been studying it since i first got interested in it. i was around 8 or 10 and that was about 45 years ago.
