So for the 2018 baseball season the bullpen cart returned. The design uses a batting helmet for the main body and the support bars are shaped like bats. The Arizona Diamondbacks were the team to debut the new wave of bullpen carts. If memory serves it was the Washington Nationals then closer Sean Doolittle who was the first pitcher to use it. Maybe he was the first visiting pitcher.
Long story short Topps made a Topps Now card to celebrate the event (there is even an Allen & Ginter card that I plan on getting) I eventually got it. I waited way too long to get it at the original under ten dollars prices. I even went through a period of it not being available on Ebay for a few months. When it finally did come back the prices were super high, higher than I like to pay. Anyway I eventually paid $15 for a copy. I almost had to go up to $20 or more. Also of interest with this card is the seller sent the Topps Now packet "case" the cards come in when you get them directly from Topps and not from some dealer who has already opened the pack to scan the card for their listings.
So here is the card:
