We don't have a publication date for this 1000 Jokes cartoon, probably the early 60s. 
Here's an idea for your New Year's celebration . . . or maybe your summer vacation! Dell published this cartoon of Don's in the August 1963 issue of 1000 Jokes.
Just a reminder . . . don't forget the milk and cookies for Santa! Don tells the story that a Christmas tree all decorated appeared magically on Christmas eve in the second floor living room of the Brooklyn house where he lived. There would be a thump on the floor while he waited downstairs with three or four of his brothers. These younger of the kids then ran upstairs to be wowed by Santa's delivery. Don adds, he never "believed" because the fireplaces were sealed and had been since his father bought the house!
. . . and a Merry Christmas! This cartoon of Don's appeared in the November 20, 1971 issue of Saturday Review. (Other SR cartoons are posted in the #4 spot on May 8, 2009, on April 18, 2010, and October 18, 2010. The latter is posting # 254 a book reprint.)
Do gag cartoons have a back story? You bet they do! Here's a good example. We know the baby's Mom couldn't have been the one to trade the baby, so we can bet it was a big brother or sister. Just picture what happens next when that Mom finds out!
This cartoon of Don's was published in November 1968 by Dell in 1000 Jokes. Remember Carte Blanche and Diner's Club? This was before Visa, MasterCard and Discover became so prevalent. We probably used more cash than credit and no one had heard of a debit card. So the idea of a credit card for the offering was pretty unique. Who would give it a second thought today?
Watch out for this lady at your holiday parties. She's probably so busy sipping Champagne she didn't even know she can't chew! Dell Publishing printed this cartoon from Don in its February 1968 issue of 1000 Jokes.
This cartoon published in Dell's 1000 Jokes in the August 1968 issue certainly is timely today. Wonder if this guy is was a laid-off techie?
Here's another "smart" purchase by Dell Publications. This cartoon of Don's was published in the February 1967 issue of 1000 Jokes. . . and this was before anyone wore bicycle helmets.
Here's an idea for husbands (partners) who don't know sizes - if you dare! This cartoon appeared in the August 1967 issue of Dell's 1000 Jokes.
We posted and counted a cartoon of Don's from 1000 Jokes, Dell Publishing, way back in May 2009 when this blog was just getting going. (See posting #5.) Don has a pretty thick folder of clips from this magazine, maybe not a 1000 cartoons, but a lot. So we will share a series of them here. This one was published in the August 1967 issue.
Do read the two jokes on the back cover here. They should give you a chuckle even if you're not a kid. This book illustrated by Don was printed by Scholastic, Inc. in 1988.
These cows that Don drew for 101 Bossy Cow Jokes should be in the circus instead of down on the farm. Or maybe they belong in New York City. They certainly are cosmopolitan cows, and we don't mean the magazine. Scholastic, Inc., published this one in 1989.
Digging deep in Don's studio we came up with Vol. 1, No. 1 of Breezy Rider, Jan.-Feb. 1971, or as the cover says "FURST FOIST [crossed out] EDITION." Don had three cartoons in this premiere edition, one of which is shown here. The magazine was published (at least once) by Colony Publishing Co., Las Vegas, Nev., with editorial offices in Encino, Calif.
