I have in my possession a cartoon sketch of a little boy asking a girl for a kiss - caption says "Say kid, I have a new brand of kisses and the samples is free". The artists signature looks like - cTwe Ivetreef - I take it to be Clive Ivetreef. There is a copyright of Edward Gross N.Y.
The picture was purchased by my parents in 1945 from a private sale and may have been reasonable old even then.
