Absolutely. The tape label has the Alto logo and full name: An Lárionad Teicneolaíochta Oideachais (Alto). Address on tape label is also correct. Alto’s main work was producing material for the Department of Education like the “Colm and Nuala” filmstrips. But I also have a few history lesson filmstrips that they produced also “The Vikings” etc. Recording bands seems to have been mostly on downtime.
