What era for these JBL speaker grill badges?

[RSchiller]

Hi, I have two sets of metal JBL speaker badges as shown, these have the metal posts on the rear - no velcro.
I'm curious what era these are from? Are the vertical ones older?

thanks to all!

Hello, looking at the JBL library it appears the vertical style stopped in 1969 and in 1970 the square ones started. Hope this helps:)
