Complete sheets or multiples with the entire row of ten stamps are not known and most probably does not exist. Even the pieces larger than 2x2 are extremely rare...
1944 Senta local provisional issue, block of ten (5x2), positions B4-8. Unique item showing the process of multiphase overprint - upper row Mi. XIV, lower row Mi. XIII. This is the largest remained piece of Senta issue known to me.
