Type of sign stand/base?

[JA23]

Anyone know what time of base or stand this is and a provider?

Google Search Results

Looks like there are a lot of options out there

Your internet search words should include "spring base sign frame images" or "Flex Sign Frame" or "Flex Sign Holder"
How many do you need? What size?

I used "Blank Springer Sidewalk Sign".... because in the results from my first search, this came up and looked the most like the OP's picture. Most of the others have a frame.

I found this frame, but OP's looks kinda like it might haver ground stakes rather than feet. I didn't see any option like that on the site. Maybe someone modified these for use in grass?
