The checklist for the 2021 Bowman Prospects has 150 cards.
Amaya and Morel are with the Cubs AA team. Marquez is having arm issues and will head to AA once he is ready. Howard was the Cubs' #1 pick last summer and will start the summer with the Cubs low A team in Myrtle Beach.
The prospect cards have the usual parallels including the Chrome version. I've had those each year, and continued the run this year.
