Reading from the graph, the approximate number of bobbleheads sold in the years 2016,2017 , $2018,2019,2020$, and 2021 were $20,35,40,38,60$, and 75 , respectively.

Beginning with 2016 and 2017, the increases (or decreases) in the sale of bobbleheads between consecutive years are approximately $35-20=15,40-35=5,38-40=-2($ a decrease of 2 ), $60-38=22$, and $75-60=15$.

Thus the greatest increase in the sale of bobbleheads was approximately 22 and this occurred between 2019 and 2020 .
