[OC] A few more logos I drew earlier

These were made soon after I learnt about Blåmba, a Blåhaj-themed provider of content for retro phones running on GSM networks at Chaos Computer Club's events since 2023. There was a dire lack of Blåhaj among these 72x14 1bpp pictures ("operator logos") you can use on the home screen instead of the name of your phone carrier.

This is a follow-up to the previous post (follow link for more details) although I drew these about a month earlier.
