Blue glass bowls w/ embossed design on sides.

I got a set of these bowls last night & struck out trying to ID them this afternoon. I thought I would post a photo here before hauling the set over to the consignment shop to sell.

I was thinking they might be a go along for some dishes, but couldn't find anything on Replacements.

I haven't really been able to get out to the stores to shop much in the past couple of years so I was hoping someone here might recognize the pattern or the maker.

The 1 in the photos below is 5 3/4" across & 3 1/2" deep. I also have 6 smaller ones that are 4 5/8" across & 2 7/8" deep.



Thanks for any & all advice or opinions!!!

 

Is that an F on the bottom?

 

Unfortunately it is not a mark of any kind. It looks like a mark made by the mold.
