Ostroznie Yeti, or 'Caccia R.B. 1-5 Missione Segreta' as it was catchily known in Italy, was the classic tale of boy finds Yeti, boy loses Yeti, boy chases Yeti in an MG TA and a Supermarine Spitfire.

Did Ostroznie Yeti work ? Well it did in Poland.

All I would say is that you'll certainly have bragging rights over your movie nerd chums if this is in your collection.

The poster is obviously cinema used, and has the 'paper tax' stamp to the right of the Spitfire prop.
