A vintage coffee substitute optical illusion

He's in a sad mood when 
he can't drink his coffee

 Now he's happy (and gotten a shave, too!) 
because he drinks Pečecká Kávovina

Since I don't speak Czeck, I used Google Translate to help, which created this amusing Coffee Haiku:

When he does not have a coffee,
which he tasty then the sad mood
And so cheerful face when kava
on the PC with the lemurs.
PCs, factory substitutes ant.
Kostelec stones

A bit helpful, and very amusing.
