These are called "Concentric Ribbed"
I have a set of white ones just like yours with a turquoise ribbed pitcher./ I noticed the crow logo on yours & mine as well are very detailed, much more so than other pieces of Akro ware.
Same # 12 highly visible on mine to, wish I could get my hands on or reference guide to the meaning of each number ??
I know there are a couple complete guides to Akro ware & other Akro products, both by Roger & Claudia Hardy, maybe I'll go ahead & get them ?? You may recognize the first names ?? The VVHTF "Jolly Roger" giant cork & the "Claudia" both Akro marbles named after them.
