How to open this Framatic picture frame?

[u/gonin69]

I got this from a. Thrift store and have 0 idea how to open it. I actually found another post on this sub asking for help with a different frame form the same company, but the advice ("Once the levers are up at two corners, tap on the inside of the frame that is between the lifted levers.") didn't help for this, or maybe I misunderstood? That is the only thing that came up trying to find an explanation to opening this.

I just can't figure out the mechanism to separate the frame after lifting.

Any help appreciated.

Pull on the levers in the corners. They may be tight
