Sizes are 5/8" to 1.25. First row items 2 and 3 are identical enamel on brass pin and stud, both on original cards. Slogan is "Boycott Hitler's Germany" showing hand crushing the Nazi swastika symbol. At the bottom is a small panel that held another word but this has been stamped over for some unknown reason and is unreadable. The first item in row 1 reads "Halt Hitler" below Star of David. This was pre-Pearl Jewish issue- beware of a repro in larger 1.25" size. Of the other eight buttons, fourth, sixth and seventh are litho. Fourth was premium from Servel Refrigerators which came with a booklet "The War Worker's Guide To Eating Fitness" in 1942. Other than row 2, item 3 which has two small wear spots and no paint gloss, the other items are Exc. to Mint. The green version "To Hell With Hitler" is rare.
