Belz in Belgium prints old interesting ads and pictures from archives. They printed this week a full page promotion of Manischewitz matzohs. On the left bottom you see
2 Sanzer einiklech promoting the matzohs. The Bardiuever Rebbe Reb Yitzchok Halberstam (I think Bardiuv is from the Gorlitz geza) said: my whole trip to America was worth it, just to see the high kashrus standard of Manischewitz. I would bless the Jews in Europe to have such kosher matzoh. The other einikel Reb Naftali Chaim of Grivetz said: by Manischewitz I saw everything done cautiously and in the best way possible. If they would know this stuff would be unearthed one day and some crazy would find it would they have said that?
