Next, a 1967 Seattle Popcorn card. These were stadium giveaways that came with a box of popcorn at Seattle's Sick Stadium. The Seattle Angels were an affiliate of the Angels in those days and Locke was up-and-down between the majors and minors. The card is about the size of Topps '75 minis and the ones that they stuck in some packs of '17 Heritage. .
The Standard Catalog of Baseball Cards says the year can be determined by the list of sponsors on the back.
The Seattle Popcorn series ran from 1954 through 1968. Here is the SCBC entry for them:
Locke has a few more oddballs floating around out there. I don't have the time or energy to track them down at the moment but over time I will probably find them. It's fun to have a project.
