Another Sidney Harris Classic!  In fact, this is probably THE classic of ALL Sidney Harris classics.  Whether you step into a Math class, a Chemist's Lab or any place where Physics, whether classical or theoretical, is being explored, this ode to the greatest "fudge factor" of them all, belongs on the wall, somewhere, anywhere, to remind everyone about the tough work ahead .  If not on the wall, at least one of the working scientists (or students, lab rats, flunkies, or minions) should be wearing this shirt!  You might want one as well.

From our most collection of most popular t-shirts!  Up for sale is what is probably the best known and best loved Sidney Harris Science/Physics/Math/Lab cartoon on a T-shirt.  This was one of the first T-shirts we ever carried when we started our Museum Shop back in 1990, and it continues to ALWAYS be one of our most consistent and best sellers to this day.  Several years ago, we had the opportunity to buy an entire special order of these shirts printed on a White shirt instead of the usual Ash Gray.  Since then, we've sold virtually every one of the White ones...except for a limited quantity still left in size LARGE only.  I need the space so I am offering these White versions for the first and last time until they are gone.  Because of the constant demand for this design in ALL other sizes, we figured that we had better list the regular Ash Gray ones as well.  These are BRAND NEW, FIRST QUALITY, preshrunk 100% cotton shirts, available in size SMALL, MEDIUM, LARGE, XL, XXL (EXTRA EXTRA LARGE, DOUBLE XL, 2XL) and/or XXXL (TRIPLE XL, 3XL).  This is an original, fully licensed design, screen-printed onto top quality shirts for durability and long life...this is NOT some cheap iron-on design.  Suggested to sell for $25.00 ($27,00 for 2XL, $29.00 for 3XL) and up (plus shipping), I am offering the regular Ash Gray ones for $24.00 each ($26.00 for 2XL, $28.00 for 3XL), while what are left of the White ones in size LARGE are on sale for $23.00 each.  [The dealer, who had originally ordered the White ones, used to sell this version through a very well known catalog for $24.95 each plus $5.00 shipping!]  Whichever you choose, our price includes free shipping to anywhere in the U.S.  You can combine this with other items that I am selling to receive a refund for each additional item after the first, once shipped.  This refund reflects my savings in postage fees by combining your orders and is based on the total weight of the items.  International buyers are eligible for the multi-item discount (WHEN YOU USE THE SHOPPING CART FEATURE AND PAY FOR ALL OF YOUR ITEMS IN A SINGLE PAYMENT!) and receive free shipping to the Global Shipping Program Center in Kentucky, USA, but are responsible for all additional fees for postage, customs, tariffs, and/or other import charges.  Any questions?  Contact me.
