This cover was posted from Tela on February 3, 1934 with a Peace cancel and D2 postmark. OCX pricing is $15. The Castaneda control signature has a multiplier of 2 so that ups the total to $30. The fact that it is a multiple with an additional stamp variety would push the value to over $40.
This cover was posted from Puerto Castilla, Colón on October 25, 1933 with a LO3a cancel unique to that city and the OCX value stands at $15. The Mejia control signature carries a multiplier of 2.5 so we are at $37.50 for this one. Probably higher for it is a multiple.
