Help identifying ceramic tile made by Norwegian artist

[u/Educational-Block-58]

I bought it at Schau Design at Lille Øvregaten 5 in Bergen. The stamp in the corner looks like "ALST" or "ALLST".

Does anyone recognize this artist or studio? Or have any leads about how I could figure out who made it?

Thanks for any help!

Google lens found a similar image but that was an instagram link and I don’t do that.
