This picture was salvaged from a discolored copy slide. Prototype of the T-25 Universal, later designated XT-25. Picture is taken as some aviation fair in the Rio de de Janeiro city. I have been unable to find a date or the exact location. Any help is appreciated. Photo via G. Bouma

This picture was salvaged from a discolored copy slide. I know nothing about this picture. Location is somewhere in Rio de Janeiro, but the exact spot is unknown. The occasion is probably an aviation fair as this aircraft was later transferred to the civil aircraft register as PP-HKJ. Any help on date and/or location is appreciated. Photo via G.Bouma
