Piggy banks made by TT Teplice
The origin (or provenance) can also be deduced by comparing. Connoisseurs call this that the signature is visible everywhere without the need for a mark. This is also the case with these piggy banks. The one on the right (or upper one with the red) was bought in Prague (€30,-) and has the brand TTT. The left one (or bottom one) does not have a hallmark but is clear of a similar mold, but larger (15.5 cm versus 13). So with almost certainty also of TTT, or TT Teplice.
